Apple Launches New Version of HyperCard, Providing Significant Flexibility,
Power and Customization Enhancements

AppleScript Support, Color, Media Integration Extend HyperCard's Appeal to
New Users

CUPERTINO, California--December 13, 1993--Apple Computer today introduced
HyperCard 2.2, a significant new version of its popular software tool that
enables users to easily create customized software solutions.  Version 2.2
represents dramatic increases in power, functionality and flexibility,
extending HyperCard's value to new and existing multimedia title producers,
educators, commercial solution providers and in-house developers.
    HyperCard 2.2 integrates a key Apple technology, AppleScript, which
enables users to automate repetitive tasks by launching, controlling and
exchanging data with existing applications.  HyperCard 2.2 also includes the
ColorTools for seamlessly adding color to stacks; WorldScript support for
creating multilingual solutions and a new "save as" option that creates
double-clickable applications which can be distributed without royalty fees. 
In addition, HyperCard 2.2 bundles ADDmotion II from Motion Works
International for easy creation and editing of animation.
    According to AppleSoft senior vice president and general manager, David
Nagel, "When HyperCard was launched in 1988 it delivered power and
flexibility that set a new standard for application development. Today, we
are extending that power and flexibility with a host of new features, making
HyperCard an even more strategic product for the multimedia, education and
in-house development markets."
    HyperCard is on over eight million Macintoshes worldwide and has been
lauded as a key Apple technology by educators and business users worldwide. 
The latest release of HyperCard extends customers' investments in their data
and provides valuable new features that significantly improve end-users'
experiences with stacks.
    "We are a two-person consulting firm specializing in on-line
documentation and multimedia development.  HyperCard's amazing power and
flexibility have enabled us to create our own custom applications which we
can fully integrate and modify as needed.  Furthermore, it is the glue that
allows us to integrate other applications such as Word, Persuasion and
Excel," said Katherine Horton, a HyperCard user at William Horton Consulting
in Huntsville, Ala.

AppleScript Functionality Now Built Into HyperCard
    With AppleScript now built in, HyperCard 2.2 provides a dramatic increase
in functionality to new and existing users.  It enables them to integrate
applications with HyperCard, providing much easier ways to manipulate and
present information from a wide range of applications.  Users can launch,
control and exchange data with a host of scriptable applications such as 4th
Dimension, MacWrite, FileMaker, Microsoft Excel, Microsoft Word, PhotoFlash,
QuarkXpress, and WordPerfect, along with over 75 others.  HyperCard supports
any Open Scripting Architecture (OSA)-compliant scripting language including
AppleScript, UserTalk from UserLand and CEScript from CE Software.
    "HyperCard 2.2 is an optimal choice for commercial solution providers. 
With AppleScript support, users can create even more powerful solutions by
extending the core functionality of HyperCard with off-the-shelf
applications," said Param Singh, HyperCard product marketing manager.  "With
the wide variety of scriptable applications available today, HyperCard users
can immediately create innovative applications to meet their individual
needs, while preserving the simplicity and ease-of-use of the HyperCard
environment."

Color/Media Integration
    HyperCard's new ColorTools enhance the useability and visual appeal of
existing and new solutions.  In addition to importing and resizing color PICT
graphics, users can select from a palette of 256 shades to color HyperCard
elements such as buttons, fields, cards and backgrounds.  HyperCard's
QuickTime tools allow users to incorporate movies into cards and stacks with
point and click simplicity.
    "The new release of HyperCard, especially with its open scripting and
color support, gives a wide range of Macintosh users access to incredible
programming power.  I am delighted with Apple's commitment to the product,
and expect to see new and existing users develop exciting new solutions for
themselves and the Macintosh community," said Danny Goodman, HyperCard user
and author of The Complete HyperCard 2.2 Handbook, coming in January 1994
from Random House Electronic Publishing.
    HyperCard continues to help multimedia authors differentiate their
product by providing comprehensive multimedia capabilities in one
environment.  With ADDmotion II, HyperCard 2.2 facilitates easy media, color
and sound editing to help users enhance the value of new and existing stacks.
 ADDmotion II is a 24-bit color paint, animation and sound extension that
integrates seamlessly into HyperCard and provides tools for controlling and
editing animations and sounds.
    HyperCard 2.2 is the premier solution for education.  With color and
QuickTime capabilities, HyperCard enables educators to create innovative,
compelling courseware while preserving ease-of-use for students.
    In addition, HyperCard 2.2 supports WorldScript, which makes it possible
to include different languages in a field or card to create powerful
multilingual solutions.  HyperCard users can script in several languages
including French and Japanese, using AppleScript dialects extensions.

Subject: StyleWriter: Grayscale vs Black&White (F)

In a previous post, I asked for advice concerning ink economy when printing
text with Grayscale or Black&White on a StyleWriter II, because I had been
somewhat confused by apparently contradictory advice in the SW manual and
ReadMe.

I had a good response, but some of the replies did show that I wasn't the
only one to be confused.

First of all, thanks to all of you who responded. (You know who you are.)
I now understand the mechanics of printing better than I did.

Some of you were interested in a summary, so I am including 2 of the
replies below, since these seem to resolve the question I raised:

                =======================================

>First, for the life of your cartridge, the best option is to put all text you
>print into a sufficiently dark gray, and then print with Grayscale on.  The
>reason is that the StyleWriter will print a full-out black (using more ink)
>if printing in black and white, than with a gray.
>
>The drawback here is that printing in gray could well be slower.  With that

>dead-black.

[Presumably, if one is printing in the background, the slowness of printing
with
Grayscale on is NOT a drawback.}

                ======================================

>Well: "in my experience" and "from my knowledge", both rather limited,
>1) quality: greyscale vs. b&w affects the quality of graphics, not text.  If
>you
>use b&w for greyscale or color graphics, you will get either solid black
>or solid white for each color.    greyscale will "halftone" things.
>2) speed: the SW II driver allegedly checks for each page whether it contains
>greyscale information or not.  If it doesn't, it behaves as if it were printed
>using B&W, which is faster--not sure if the printer really is faster, or if
>the driver requires less CPU power to generate the halftones.
>3) ink usage:  if you happen to print graphics in B&W you'll use ink faster
>if there are dark colors, since you'll get lots of solid black areas
>
>>From #2, I assume that in printing a page of only B&W stuff (text, graphics,
>whatever) the printer will behave the same with either B&W or greyscale
>selected.  And from that, that the ink consumption won't change.  However,
>if you do encounter a color graphic or colored text or whatever, your ink
>consumption should be lower in greyscale mode, since it will both to halftone.
>
>This may be all washed up, too.  I don't have a reference on #2, but I've

This is a text file that describes how to build a case to hold multiple 
internal SCSI devices using a PC case. The cost is around $100 (US) and
can hold 4 or more devices. The text file gives possible part numbers and
hopefully answers possible questions from the average user. My system has
been working for >3 months without any problems. If interested, read it.

 SCSI CASE 1.1

Using PC Case to hold SCSI Devices for a Mac system.

INTRO:
The price difference between internal and external SCSI devices is about $50 to
$100. The cost to build a case to handle numerous internal SCSI devices can be
under $100. This will reduce the cost to add other devices. This report should
explain the cost, the material, and the work required to complete this task.

CONCEPT:
External SCSI devices come with a case, a small power supply, a loop-thru SCSI
connection, and maybe some type of termination. The PC case will provide the
mounting and the power supply for multiple SCSI devices. One ribbon cable
assembly is required to connect the devices together and to the rear of the
case. A shielded SCSI cable can be purchased to connect the Mac to the PC case.
The last device on the chain in the PC case will need to terminated. If other
SCSI devices that will not be in the PC case are used, they will need to be
located between the Mac and the PC case on the SCSI chain.

MATERIAL:
1)  PC Case - a mini-tower case with a 250W or more power supply can be
purchased for <$60 ($45 is a good price new). It should come with miscellaneous
hardware for mounting the devices. The power supply should be prewired with
connectors for providing power to numerous SCSI devices (typically 4 or more). 
2)  External SCSI Cable - a DB-25 to 50 pin centronics for about $15
3)  50 Pin Ribbon Cable - 5 feet or less. The quality is up to the buyer and
starts around $1/foot. (Digi-Key  R028-5-ND is $4.79 for 5 feet)
4)  50 Pin Centronics Connector - the external connector on the PC case at one
end of the ribbon cable. (CHAMP Latch Bail Lock - Amp # 553603-1; Digi-Key
A1569-ND $5.20)
5)  [Optional] Bail Lock Hardware - the hardware to lock the centronics
connectors together; other methods like screws can be used. (Amp # 552561-3;
Digi-Key A1517-ND $1.67)
6)  50 Pin Socket Conn with Polarizing Key - the connector that snaps onto the
ribbon cable where needed. If you have five devices, you need five connectors.
(Amp # 1-746286-0; Digi-Key AKC50T-ND $3.57)
7)  [Optional] Strain Relief for part #6 - at least one should be used for the
end of the cable, but the rest aren't needed if care is used. (Amp # 499252-4;
Digi-Key ASSR50-ND $0.77)
NOTE: Please verify these part numbers before ordering to make sure that the
proper part is ordered. Many different equivalent parts from other makers can
be used. Better quality (i.e. gold contacts) can be used to, but it increases
the cost.

COST:  (all cost are continental US dollars)
$ 60       PC Case 
$ 15       SCSI Cable 
$  4.79    Ribbon Cable 
$  5.20    Centronics Conn 
$  1.67    Bail Lock 
$ 17.85    Five Socket Conn 
$  0.77    One Strain Relief 
------- 
$105.28    Total (but your cost may vary)

SCSI CABLING: This is one area that usually worries most people out of the fear
of destroying their device. Buy an official Mac SCSI cable that is a 25 pin D
to 50 pin centronics. The rest of the way, just match up all of the pin 1's.
The other pin numbers will not match up due to the numbering convention. The
ribbon cable should be marked to show pin 1. Closely examine the 50 pin
connectors and look for the pin 1 marking (they all have them). Always keep pin
1's matched up and it will be correct. The connectors must be keyed to prevent
plugging them into the drive wrong. The ribbon connectors should only be
snapped on once so be careful. Reusing ribbon connectors usually results in a
less reliable connection and might cause opens or shorts. For putting the
connectors on the ribbon, try using a vise whose head is the length of the
connector. Uniform pressure along the connector helps make a good connection.
Also, make sure that the connectors are straight when putting them on the
ribbon to prevent misalignment. Before hand, figure out where you plan to mount
the drives and how the ribon will be routed. Be sure and consider future
additions as you will use the same cable. All of the connectors don't have to
be put on the ribbon at the beginning. Leave some space and when the new drives
are added, put the connectors on then. This probably would require removing the
whole cable assembly to add the additional connectors. Be conservative in the
amount of ribbon cable used. Leave enough for additions, but too much can hurt
the SCSI bus. No more than 5 feet should be required. The maximum specified
limit length of the whole SCSI chain is 20 feet, but reality says that 15 feet
is a more pratical upper limit. Use the SCSI reference table below if you
desire to double check the connections.

Note: The ground pinout may be different than the sample cable used to create
this table.

OTHER CABLING:
The power connectors on the power supply should be the standardized 4 pin keyed
connector and plug right into the SCSI devices. There will be some other power
connectors that can be ignored as long as they don't short out somewhere. Note
that some power supplies have open circuit cutback. A load on the 5 volt and
maybe the 12 volt line might be required to get the voltage outputs up to the
rated levels. This load may also be needed in the completed case if the
installed SCSI devices don't draw enough current. A 10 ohm >2.5 watt resistor
(P=(5^2)/10=2.5W) on the 5 volt line should provide enough loading. Most PC
cases have a few LEDs with two pin connectors to indicate power, turbo, and
reset. These can be connected to the 2 pin headers (usually found opposite the
50 pin connectors) on the harddrives to indicate disk access. The correct
polarity is required to get the LED to work, but the wrong polarity should not
damage anything. So just trying any polarity to see if works should be
acceptable. Most new PC cases won't even have the power switch pre-wired to the
power supply. The provided instructions should be used to complete this job.
Extreme care should be used when dealing with AC power lines.

MOUNTING:
The PC case should have plenty of mounting screws and brackets for supporting 4
to 5 SCSI devices. Be sure that the mounting doesn't distort the SCSI device's
case which could cause damage. Also make sure no loose cables or other objects
are allowed to cause a short on the device. Most harddrives will function just
fine no matter what the orientation. The key is to format the drives in exactly
in the same mounting used for regular drive operation. Remember that the last
SCSI device needs to be terminated. The mounting for the external centronics
connector is probably the hardest part of the whole deal. The connector doesn't
easily fit anywhere. A custom cutout in the back of the PC case is the cleanest
approach, but sticking it through one of the card slots is the easiest. Don't
let the ribbon cable stick through the case because the metal wall could wear
through the cables insulation cause a short.

SCSI IDS:
The Mac SCSI allows 8 IDs. The ID 0 should be used by the internal drive and 7
should be the Mac. That leaves 6 others (1-6) that can be used for other SCSI
devices. The 6 pin (2 rows of 3 pins) header on the devices is used to set the
ID and is a three bit binary number. Only one device can be used for each ID or
the bus will not funciont and might cause loss data. Note that if more than one
device arbitrates for use of the bus at the same time, the device with the
higher ID gains control first. Once a device, regardless of ID, gains control
of the bus, no other device can interrupt that session.

TERMINATION:
The first and last device (by physical cable location, not by ID) in the SCSI
chain must be terminated. The internal harddrive should be internally
terminated. A row of 24 pin sockets is typically located on most harddrives
near the 50 pin connector. These sockets hold the line termination resistor
arrays used for SCSI termination. If the resistors are in, the device is
considered internally terminated. If not, then it is unterminated. Some reports
state that some exceptions exist to the termination rule. If the SCSI chain is
<18 inches, then terminate one end. If the chain is >10 feet, then a terminator
in the middle should be added. Always terminate just both ends first and only
change if problems exist. Three 8 pin 220/330 ohm line termination resistor
arrays are typically used to provide the termination. The faster the mac is and
the more devices there are attached to it, the more important termination is.
[Some info from Mac Bible]

SCSI DEVICE ORDER:
While the SCSI bus should be a plug-n-play interface, some problems have been
noticed in different configurations. Some devices will not function properly
with other devices. The physical order on the SCSI chain sometimes causes
problems with some devices. This SCSI PC case should change any of these
conditions. If the devices functions properly in a standard setup using
individual cases and cables, then it should work in the PC SCSI case.

SHIELDING:
The shielding of the case and the ribbon cable is a concern that many people
have. External devices have metal or conductive walls and have real short
ribbon cables. The PC case should provide the necessary shielding required for
the outside world. The major question is the shielding requirement from device
to device and from cable to device. For most systems (almost all home systems),
this PC case system will provide plenty of shielding and the SCSI communication
will function properly. The PC case system may cause SCSI re-tries and other
problems with the SCSI bus if not properly implemented. The use of a SCSI test
program can be used to conduct timing tests to see if the PC case system is not
performing properly.

POSSIBLE QUESTIONS/PROBLEMS/WORRIES:
1.  Heat Dissipation - If you think (or notice) the case will get too hot then
add a fan. The speaker mounting might be a good place to mount a fan. Consider
the air flow as some devices should not suck in outside air due to dust. A DC
fan could easily be powered by the internal power supply. The PC power supply
should be able to handle the 4 or 5 devices without a problem. Check the power
consumption of each device to be sure.
2.  SCSI Loop Thru - You can make this system with a loop thru by adding an
external connector at the end of the ribbon cable. This greatly increases the
length of the cable and slightly increases the cost and work, but it is
definitely doable. This may be required if you have another device that must be
at the end of the SCSI chain.
3.  On/Off Power - All of the devices mounted in the PC case will get powered
on when you power up the supply which is a feature of this system. Extra 2P2T
switches could be wired up to the power of certain drives to provide any
additional on/off control that is desired. Note that some devices must be on
for the SCSI bus to work at all. The SCSI case should also be powered on prior
to the computer and allow to come up to speed.
4.  Device Verifcation - Each SCSI device should be verified in the system
without any other devices connected. Make sure that each one works and then add
them one by one until your system is complete. A lot of wasted debug time can
be spent on a system when just one device is defective.
5.  Risk/Garrantee - If you don't have the money to replace anything that you
damage, then don't attempt to make this SCSI case. While the system is
relatively simple to complete, any time you handle computer devices there is a
risk factor. Some (or many) stores or dealers may not stand by their warrantee
if you use their device in this non-standard system. It is also difficult to
get salesmen to even understand the setup.
6.  Apple CD300i - This drive will easily mount in one of the 5" slots of the
PC case. No extra mounting hardware is required even a salesmen will try to
sell you one. The device will fit flushly on the front and doesn't need a cover
plate. A unique cable will need to be made to get the rear audio output mounted
on the back of the PC case. The front mini-headphones connector should be good
enough for most users. Note that some internal CD drives will not have the
front connector or the volume control.
7.  SCSI Speeds - The faster the SCSI speeds, the better the SCSI cabling must
be to prevent problems or delays. This PC case system is not the best, but it
is probably better than some SCSI chains out there already. It should not cause
any noticeable difference in your SCSI performance. The quality of each system
depends on how it is put together and what devices it uses. This PC case should
be acceptable for most everyone. If you are really worried about your SCSI
speed, then don't attempt to build and use this system.
8.  Other Jumpers - There will probably be some other jumpers on the
harddrives. Don't change their configuration unless you exactly what you are
doing. Drive manufacturers should be able to provide any additional information
on the extra jumpers.

COMMENTS:
The SCSI PC case is a great way to add devices and minimize the cost. This
report should be a valuable aid to anyone considering the idea. You should
think everything through clearly for yourself before attempting this adventure.
No promises are made. Other people have completed the same type of system with
success. If errors exist within this document, please except my appology and
inform me of my errors. More email help is available just by asking. I would
like to hear from anyone that found this report to be beneficial. Email me if
you can to tell me whether or not I wasted my time writing this report. Good
luck.

report/sys71_vs_70_speed.txt

This submission is a compilation report on the speed of the Mac OS System
version 7.1 versus System version 7.0.1 on various Mac models.

The motivation for this report was the many rumours going around about a
performance decline in SANE performance on some machines.  Since changes in
performance of the System has a direct effect on users' productivity, I
thought it would be useful to compile actual tests so that people could refer
to actual facts when making the decision on whether to upgrade to Sys7.1 or
not.

The tests used are the suite of benchmarks performed by the program
info-mac/util/speedometer_31.hqx.  These benchmarks are only valid for
comparison purposes between mac models and should not be used to compare to
other platforms.  Also, when looking at ANY benchmarks, you should always keep
in mind that no single benchmark ever tells the whole story.  If you do not
understand the meaning of a particular benchmark in the following listings, I
strongly urge you to download Speedometer and read the screens presented in
the on-line help feature.

The machines tested here represent only a small subset of the growing family
of mac models.  Still, a fairly good cross-section of machines are
represented: The Mac LC, Mac IIci, PowerBook 170 & Quadra 700.  I would love
to have included more machines, but these are the only reports that have been
submitted to me so far.  As I am about to leave town on research for a few
weeks, I can not wait for more & thought I would go ahead and submit these.

Short summary of results:  The details vary from machine to machine, but the
bottom line seems to be that there is not a tremendous amount of performance
difference between the two system versions.  Sys 7.1 IS about 10% faster at
quickdraw graphics on the Quadra, but in all other tests the differences are
small, with a few exceptions here and there.  See individual results for
details.

I would like to thank Murph Sewall, K. David Hawksworth & Daniel Schwalbe for
their help in assembling this report.

Tests performed by : Mel Martinez  mem@jhufos.pha.jhu.edu

I performed 4 different tests with the Quadra 700: Sys 7.0.1 w/Extentions ON,
Sys 7.0.1 w/Extentions OFF, Sys 7.1 w/Extentions ON and Sys 7.1 w/Extentions
OFF.

I found very little performance difference except for quickdraw.  In other
tests, sys7.1 was *slightly* faster than 7.0.1, but not tremendously.

Tests performed by: K. David Hawksworth  khawkswo@magnus.acs.ohio-state.edu

Here are Speedometer 3.1 results comparing System 7.0.1/Tuneup
1.1.1 vs 7.1 on my Mac LC.  7.1 is on my 40 meq Quantum internal
drive and 7.0.1 is residing in a 50 meq partition on my Futjisu
90 meq External.  I'm not sure what influence the drive has
on Speedometer results.  There is a difference in disk performance
between the two drives according to Speedometer.

At any rate, I hope these measurements are useful to you.  I was
very suprised to see 7.1 give slightly better results.  My perception
has been that 7.1 runs a *tad* slower than 7.0.1/tuned.  I quess it
must be all in my head. :-)

				Mac IIci tests

************************************************************************

Tests performed by:  Daniel Schwalbe G00017@MSUS1.MSUS.EDU

I broke down over the weekend and installed system 7.1. Very smooth

installation. 

I ran some timing tests using a math program called Maple and I got
about a 2% speedup with 7.1 which was about the improvements in FPU
benchmarks that speedometer showed.  The slowdown in Math ratings 
that speedometer showed did not seem to affect Maple in the few 
tests I ran.

Also, the first time I ran the tests with 7.1, I got a disk rating 
of 1.0.  After removing a 2.5 megabyte temp file the installer left 
behind in the system folder, I got 2.17.

Following are speedometer results.  I restarted the machine with the 
extensions off just before running each test.

			PowerBook 170 tests

Tests performed by:  Murph Sewall  SEWALL@UCONNVM.UCONN.EDU

Today was the day I backed up my hard drive and installed 7.1 on my PB
170.  I ran the first benchmark and realized I still had the processor
set for 16 MHz, so I went ahead and ran the comparisons at both speeds.
I ran the tests with Extensions Off for maximum comparability, but the
numbers pretty well match my earlier machine records which I did with
the full load of extensions.  The 7.1 vs 7.0.1 figures don't look much
different to me.

It also turns out to have been a good idea to buy the PowerBook RAM
upgrade.  With all extensions or no extensions, 7.1 takes a little MORE
RAM on startup (about 60K more).  Perhaps 7.1 will prove better at
memory management, and won't fragment the heap the way the earlier
version do.

Subject: Shareware Survey


Text item: Text_1

     While trying to enhance my virtual sensitivity for CPU multicultural 
     issues  ;)  I came across this on (~shudder~) IBMPC-L and thought the 
     Info-Mac folks might enjoy it:
     
     quoted material follows-------------------------------------------
     
From: corbier@satelnet.org (Daniel Corbier)
Subject: Shareware Author & User Case Study (brief summary)
Date: 16 Sep 1994 03:44:21 -0400

The following is a very brief summary of the Shareware Author & User
Case Study.  Copyright 1994, by Daniel Corbier.  All rights reserved.
Answers are based on survey responses from shareware users, and
successful authors.  Standard disclaimers against liabilities apply.

Q: What is the average price users pay for shareware programs?

Users pay between $5 and $200 (US) per program.  The most popular price
is $25, and the average price paid per program is roughly $30.

Q: Which methods of payment are used for registration?

Most shareware registrations are done by check, followed by credit
card.  Some customers use both, while others indicate a strong
preference for one over the other.  People also register by money
order, Compuserve, online doors, and cash.

Q: How much time does it take users to evaluate shareware programs?

Some register after the first use, while others register after years.
How soon a user sends a payment depends on factors such as frequency of
use, learning curve, personal cash flow, and more.  Users do not always
start using programs right after downloading them, neither do they
always keep track of how long they evaluate these programs.

Q: What prevents users from registering shareware programs?

"Unreasonable price" represents by far the most common reason for not
registering.  It's followed by crippling, and then payment difficulties
(currency exchange, etc...), nag screens, lack of support, unreachable
authors, bugs, bad documentation, lack of money, expiration, laziness,
too few reminders or promised features, inadequate upgrade policy, and
bad author attitude.

Q: Which factors motivate users to register?

High quality, usefulness and then understanding/appreciation of the
shareware concept or honesty are mentioned the most.  Affordable price
comes next.  Other motivating factors include support, full
functionality, good interface, free upgrades, extra features, reminder
screens, good documentation, positive author attitude, easy methods of
payment, printed manual, and limited time offers.

Q: Which incentives are used by authors of programs users register?

Users mention extra features the most, then free upgrades, followed by
printed manuals.  Other incentives include nag screens, full
functionality, support, quality, usefulness, delays, random key press,
price specials, source code, and expiration.

Q: What percentage of users register?

A shareware program gets registrations from anywhere between 0% to 80%
of its users.  Registration rate depends on many factors.  A number of
successful authors estimate that 5% to 10% or so of their users
register.

Q: What kind of people register?

Some programs are mostly registered by businesses & corporations,
others mostly by home users, others mainly by sysops, etc...  Some are
registered by a good variety of users.

Q: When does the first registration come?  When does success come?

The first registration usually comes within a few weeks of first
release.  It takes between 8 months to several years before shareware
programs have a chance to become successful.

Q: Do customers usually contact the author before registering?

Most users simply say "no".  Some do usually contact the author,
however.  Others check with the author only if there are problems that
need to be resolved or if the program is old.

Q: What are primary sources for obtaining shareware programs?

Most users mention BBSes as a primary source.  Authors also mention BBS
distribution as a primary source of registrations.  The next most
popular choice is FTP.  Other sources mentioned include CD-ROMs,
commercial online services (Compuserve, AOL, BIX, ...), disk vendors,
friends, racks, and cover disks.

For an in depth explanation of what makes users register, and what
makes some authors successful, obtain a copy of the Shareware Author &
User Case Study.  On BBSes the file name prefix is SAUCS1.

Info-Mac guidelines

o We do not accept commercial announcements of products or services.
  We also do not accept password protected packages as we are not an appropriate
  distribution site for your profit making ventures. However, we welcome
  demonstration copies of all such products.

o Please do not submit materials that are sexually explicit or may otherwise be
  deemed as for adults only. The Info-Mac archive is NOT for adults only.

o Do not post files or messages to the Info-Mac Archive via comp.sys.mac.digest.
  it will cause you and us headaches -- FTP and email are much more reliable.

o Do not send your files to each of the different MacGifts addresses as they all
  point to the same distribution list. For example, files sent to
  macgifts@info-mac.org
  and to macgifts@umich will result in two copies arriving at Info-Mac and 
  at UMich. We will also automatically forward all files left in our FTP drop
  box to the rest of the MacGifts distribution list; so, please do not send
  files to MacGifts and also FTP it to us.

o Please do not include other complete programs within your submission. For
  example, there is no need to send BBEdit or Adobe Acrobat Reader again as we
  already have these programs at Info-Mac. A simple pointer to these already
  archived programs would be best.

o Whenever appropriate, please indicate the hardware requirements for submitted
  applications. For example, indicate if the program expects an FPU or the PPC
  processor.

o If you submit something and later decide to retract it (or replace it with
  another message), you must send a note to
  <mailto:archivist@info-mac.org>
  Do NOT mail to info-mac because we usually read that file in chronological
  order and will likely miss your subsequent correction.

o Please keep signatures to a minimum. Long ones are frustrating to those
  of us on slow modem connections! 80 characters is our preferred
  limit, although 160 characters is fine if the signature is just the facts.

o Please do not prepend [*] to your subject lines -- we will do that for you.

o To send us a binary, first compress and BinHex your file, and then write
  a text blurb to be put in the digests announcing your file. Send the text
  and the BinHexed file to us as ONE message, if at all possible.  Remember,
  use a compression program to help us save on disk space. Note that text files
  smaller than 32KB do not need to be compressed or binhexed. Also, please send
  only one attachment per email message. As some programs will automatically
  binhex or otherwise encode an attachment, please take care not to encode your
  files twice.

o Describe your binary posting accurately, but be concise. More detailed
  information belongs in a document included with your posting. We may edit
  descriptions longer than 20 lines, and we will certainly curtail those that
  are longer than 50 lines. Binaries that do not include a description
  will not be accepted in most cases.

o To submit a file greater than 800K, or to avoid submitting by (and
  segmenting for) email, send email describing the file to
  <mailto:archivist@info-mac.org> and upload it to
  <ftp://macgifts:macgifts@info-mac.org/>
  As with emailed submissions, non-text files must be binhexed.

o Please don't be cute with the "(This file must be converted with BinHex 4.0)"
  line. If you change the words, it messes up everyone's software.

o Use version numbers to keep binary updates in order. If you are posting
  a minor update to a very large file, consider using the UpdateMaker program
  (in /disk) to create a small update document instead of making people
  download the whole thing over again. However, if the resulting update
  file's size is a significant percentage of the size of the original,
  say over 25%, please just send a complete new package.

o Choose a name for your binary - the shorter, the better. This name should
  be the Subject: of your mailing. If it's not obvious, tell us which
  directory you think it should go in. And don't make the subject line
  too long; keep it less than 50 characters or so. If possible, also include
  a three to five word description in the subject line.

o Don't assume a reader is familiar with a binary.  Updates still
  should contain a short description of what a program does.

o Please post programs only if you feel they are of general benefit to
  the Macintosh community.  This will help reduce the load on our end.

o Check your binaries for problems before sending them.  Make sure that
  they are complete and virus-free. Use the latest version of Disinfectant to
  check for the known types of infection. Disinfectant is located in our vir/
  directory.

o If possible, specify whether your binary may be included on the
  commercially available CD-ROM of the archives. Contact us for further
  information about these CD-ROMs.


Thank you for your interest and help,

Title  : RESEARCH BREAKTHROUGH FOR FLAT-PANEL DISPLAY DEVICES ANNOUNCED
Type   : Press Release
NSF Org: OD / LPA

              RESEARCH BREAKTHROUGH FOR FLAT-PANEL
                    DISPLAY DEVICES ANNOUNCED

     A recent research breakthrough in reflective, front-lit
displays promises to lead to significant and noticable
improvements in laptop computers and other flat-panel display
devices.

     The prototype liquid crystal display which may replace
today's more bulky and power hungry back-lit displays was
invented by scientists from Ohio's Science and Technology Center
(STC) and the Liquid Crystal Institute.  The National Science
Foundation (NSF) established the STC program in 1987 as a means
to strengthen U.S. economic competitiveness by encouraging
partnerships between the basicascience programs of academia and
industry.  Ohio's STC is one of 25 nationwide, and is located at
Kent State University.

     Like each of the STCs, the one in Ohio was created with a
specific goal in mind; to pursue liquid crystalline research.
The new technology is the result of collaboration by several
scientists working together at Kent State.  It has already
attracted the strong attention of the multibillion dollar display
industry, which anticipates smaller, lighter and more energy
efficient lap top computers and other portable display products
producing remarkably sharp images which can be viewed easily even
in bright sunlight.

     According to Dr. J. William Doane, one of the inventors of
the liquid crystal display, the key to the new technology is that
it does not require back lights.  "Back lights are bulky and
power hungry, draining most of the power from the batteries in
devices like lap top computers," he said.  "Eliminating the need
(for back lights) means a device can run substantially longer and
will be lighter in weight."   Another feature exclusive to the
new technology is that it has full memory; an image will remain
on the screen indefinitely without needing to be "kept alive"
electronically.

     The new material -- named "Polymer-Stabilized Cholesteric
Textures" -- is suitable for use in any flexible plastic display,
from computer screens to signs of every size.  Plastic displays
would be lighter and thus more portable than current liquid
crystal, flat-panel displays, which are made on heavier and
breakable glass.

     Patents have been filed for the new liquid-crystal
technology, which was invented by Drs. Deng-ke Yang and L.C.
Chien, both senior research fellows at the Liquid Crystal
Institute, in collaboration with Doane.

     "Clearly a promising new direction for future flat-panel
display technologies has emerged" from the institute, said Bill
Brinkman, executive director of the Research and Physics Division
at AT&T Bell Laboratories, Murray Hill, N.J.  "While raising
interesting fundamental questions for basic research, Kent State
University's prototype panel . . . has many features we want to
see in future display technologies that are particularly suitable
for portable applications -- light and robust, low power
consumption, and cheaper to manufacture."

     Dr. William Harris, the NSF assistant director responsible
for the Ohio center, said the recent breakthrough demonstrates
how society can benefit when a partnership involving academia,
the state, and the private sector is successful.  "The
achievements by the scientists and students in this STC are
first-rate and indicate the importance of interdisciplinary
approaches to modern science as well as potential long-term
benefits to the nation and to Ohio," said Harris, head of the
Mathematical and Physical Sciences Directorate at NSF.  "When we
are able to encourage cooperation between university research
teams and industry, we are providing a unique training ground for
future scientists and engineers -- the undergraduate and graduate
students."

     Harris added that, in addition to training future leaders,
such cooperative efforts can also directly benefit industry.
"When breakthroughs of particular importance (such as the liquid
crystal display) are made, the NSF-supported activity contributes
to the marketplace because the result has the potential to
generate technical employment in the private sector."

Subject: Word or Nisus(Summary of answers)


Hi! Netters.

Few weeks ago I sent a message at info-mac about word
processors.
I received so many answers that I cannot send a personal reply to
each of them. I received so many answers and so many of them were
full of attention, full of details and explainations that it make me
feel great.

So I think the best way to say a usefull "Thank you" is to give you a
summary of answers. ( Upon request I could send all the complete
answers I received to personal e-mail address)

It is not possible to summarize all the comments, details and
explaination about each word processor. So I decided to give you a
statistical view of what I received.

Before doing it I must warn you about the fact that these "statistics"
are based on particulars answers to a particular question, so they are
certainly biased a little bit. Moreover this bias is probably distorted
by the way I compiled answers. So if your favorite word processor
received a low score, please don't be angry, but try to get the  sweet
feeling of the forever ununderstanded poet, alone with the truth  and
with his/her thousands of friends. Also you should be aware about the
fact that these statistic compare very different things: small word
processors, large word processors, and software for edition.
Incidentally, this is a very deep philosophical problem which bug me 
all the time and prevent me from sleeping... If you compare totally 
identical things, it is useless... If you compare completely different 
things, it is meaningless... How things must be different and how they 
must be similar for a comparizon to be valid ?????? 

To fix your mind, I reproduce here the text of the question I
sent to infomac.

****************
Subject: Microsoft Word or Nisus?

I plan to buy, learn, and use a word processor, particularly
for a doctoral thesis which will contain text, graphics and
pictures. I have a limited time for that job, so I absolutely
must not do a mistake with the choice of the word
processor I will use. Is there other word processors better
than Word or Nisus? What Nisus can do that Word cannot and
vice versa? Which one should I choose?????

Thank you very much!

*****************

Now the statistics! Let me explain shortly the way I did that.

When someone recommended a particular software, I gave it a 
+1 score.
For a non recommendation, a -1 score were allowed.
For a neutral opinion, I gave a 0. (It happened when one talk about
several word processors)

After that I compiled the results and normalized to 100%.
This gave the unweighted column. It is the base for others columns.

Second, I thought that opinions of those who knows and use several
word processors should be considered more strongly. So for those how
knows n different software, I gave a weight of n to their answers.
This gave the linear weight columns.

Finally, it seems to me that the opinion of those how knows, say,
10 different software is better but probably not 5 times better
than that of those how knows 2.  Deeply inspired, probably by
information theory, I used (log in base 2) n weight. This gave the
logarithmic weight columns.

Note.( Some results may seems inconsistent; for exemple,
unweighted and logarithmic weight for Nisus are the same!
That is because I normalised each columns to 100%.

Here are the results!
( To see the goods numbers in the goods columns,
display it with a font like Courier)

Subject:      hp deskwriter cartridge refill



This text describes how to refill your Deskwriter or DeskJet ink cartridges.
It is a summary of experiences by different people.

1) Why to refill your cartridges ?
----------------------------------

Deskwriter cartridges are pretty expensive. But there is a quick and easy
way to refill your cartridges yourself

2) Why not to refill your cartridges ?
--------------------------------------

So far I have never heard of anybody damaging his deskwriter by refilling
cartridges. But HP doesn't recommend it.
Also, the new HP ink is more 'water proof' than any kind of refill. So if
need more or less waterproof print-out, you'll need to stick to HP.

3) When to refill ?
-------------------

As soon as you notice your cartridge is running dry (printout becomes faint,
lines are missing ...) you should refill your cartridge. It's better not
to let the cartridge run completely dry, and you should certainly not let
an empty cartridge sit on a shelf for some time before you refill. Some
people systematically add ink to their cartridges to ensure it never runs
dry.

4) How many times can your refill ?
-----------------------------------

After a number of refills, the printing nozzles become blocked by dirt and
the refill will not longer work. Usually you can expect about 3 to 5 refills.
I've been told that the thermal-pulse resistors in the jet
mechanisms will tend to wear out after 5 refills or so... this will lead
to dots that don't print.  [If you run the printer self-test, the
printer controller runs a test-pattern, and will actually print the jet
number of any jet-resistor that's not drawing the appropriate amount of
current... so you can tell the difference between a clog, and a jet
problem such as a burned-out resistor or a dirty contact pad.]


5) Which ink to use ?
---------------------

Sheaffers's Skrip Jet Black ink seems to please most people. Alternative:
Park Quinck Permanent Black.But any water-soluable ink should do.
NEVER ever use india ink, because this uses solid suspended particles which
almost immediately clog up the nozzles.
Print-out is generally a bit less sharp than original HP ink, because the ink
spreads out more. It also takes a bit longer to dry. Smuding is worse
than the new HP ink.

6) How to refill ?
------------------

* always remove the cartridge from the printer
* be sure to place some cloth on the surface where you refill , in case of
  leakage.
* get a syringe with a needle of about 4cm long.
* fill the syringe with about 10cc of ink (less if you refill systematically).
* the cartridge contains a sponge ink reservoir.Insert the syringe into the air
  hole on top of the cartridge (in the green arrow) You should make sure the
  needle penetrates the sponge as deep as possible (about 4 cm).Make sure
  you do not block the air-hole completely.
  Do not try to refill by just injecting some ink on top of the sponge. You
  should always penetrate the sponge !!!! All difficulties experienced
  while refilling seem to originate from trying to let the ink
  soak in from above.
* SLOWLY fill the cartridge. If ink starts leaking, stop filling.
* put cartridge back into printer and run the priming cycle.

7) Professional refill kits
---------------------------

Some companies offer professional refill kits. Usually these are a kind
of accordian-like syringe with an injection tube of the correct length
which contain enough ink for one refill. These refills are usually quite
expensive, and the question remains if the ink they contain is any better
than fountain pen ink.
You could buy a professional kit once, and use the empty kit
to refill the cartridges with fountain pen ink.This way you always inject
the right amount of ink, at the right 'depth'.


8) miscellaneous notes
----------------------
   Hewlett Packard recommends that the ink cartridges NOT be
   recharged for the following reasons:
1.  Fountain pen ink dries with a crust, clogging up the jets.  This
    would obviously result in erratic performance.  This crusting
    will also contribute to a clogging of the priming tube.  Without
    a properly functioning priming tube, the cartridge's jets will not
    have the opportunity to clear themselves prior to a print job,
    resulting in erratic operation.  [note that the Hewlett Packard
    ink also crusts...also, the alleged special ink from HP is not
    available for purchase]
2.  The clogging will also leave deposits on the special "wipe"
    platform which cleans the cartridge as it travels across.
3.  More than likely, DeskJets found with these deposits will have
    voided warranties.

I have been told by a fellow netter that some ink manufacturers
incorporate cyanide into their ink.  I presume that this is done
to inhibit microbial growth so as to improve the shelf life of
the product.  Given that the DeskWriter cartridge mechanism works
essentially as an atomizer, the possibility exists that the
cyanide concentration in a small enclosed room could reach poten-
tially dangerous levels.  Therefore, one should be most cautious
when selecting the type of waterproof ink for re-inking these
cartridges.  I strongly recommend that you call the ink manufac-
turer to find out if they use cyanide in their ink preparation.
If not, you should at least ventilate the room in which the
printing is done.


Thanks to everybody who helped me collect this info !!!

Subject: Translations available through DataViz MaclinkPC v. 8

Dear Moderators,
Here is an update to info-mac/cmp/maclink-pc-formats.txt.
Please replace the old version with the following, and a title of maclink-pc-8-formats.txt:

FAQ - How do I convert from PC to Mac and Mac to PC?

DataViz MacLinkPlus 8.0 is one of many solutions, if others exist that can do all the following for less I would like to know:

1. Will convert to/from the most popular versions of MS-Word and Word Perfect including WP 6.0 PC, MSWD 6.0 Mac, MSWD 6.0 PC, WP 3.0 Mac, MSWD 5.1 Mac. 
2. Transfers data over serial RS232 cables (included with software).  Will translate before or after transfer.
3. Given two modems and two phone lines, will transfer data to be translated to guest machine, or translate before sending to guest machine, and transfer data over there.
4. Includes Apple PC Exchange 2.0 as part of package.
5. Includes DataViz FileView.
6. Translates before transfer to, or after receiving files from non-Windows MS-DOS machines (such as 8086, 8088 and most 80286 processors).  Some of the features may not be available for these earlier made machines, read documentation carefully before using on non-Windows MS-DOS platforms.   If using 5.25 Inch floppy drive PCs, ask DataViz for special disks for installation of transfer software onto those PCs.

7. Translations include:

PC  - Mac  - PC  (most formats are translatable both ways, as well as within the operating system in question)

Hope this is helps anyone looking for translations.
