Subject: PowerBook Keyboard Remapping



These files explain how to make the row of function keys on your 
PowerBook (anything beyond the 100 series, unless I hear otherwise)
serve as PageUp, PageDown, Home, End, and Forward Delete.

You'll wonder how you ever did without them!

This version includes instructions which work with System 8.

From: macbrick@knoware.nl
Subject: Apr�s Fax 2.0

Suppose you have a Fax-modem and you want to receive a fax late at
night or during your absence. Up to now the only way to do this was to
keep your Mac running at all times. No longer.

PreFax is a piece of hardware that enables soft power on/off Macs to
be turned on when the attached modem receives a telephone call (or fax
call). The Apr�s Fax control panel shuts down the Mac after a
designated period of time if the Mac was brought to life by the modem.
Together PreFax and Apr�s Fax can be used as an unattended fax
receiving machine.

New in version 2.0
Apr�s Fax can now tell an extension manager (not included) to only
load the extensions necessary to receive faxes. PreFax 2.0 fixes a
problem on newer Macs. Newer Macs, and those running system 7.5.1 and
up, can be shut down by pressing the power key on the keyboard. This
had an annoying side effect with the original Prefax hardware. This
version contains a fix.

Subject: AT&T DataPort 14.4K Report 

The AT&T DataPort 14.4K modem has generated a lot of interest on the
newsgroup comp.dcom.modems. An external model of this modem with Class 1
fax capability (including cable and QuickLink II fax software, yech!) is
being advertised in MacWeek (3-08-93) for $299. The offer is only good
through April 30, 1993. If you qualify under the Sysop program, your price
drops to $222. In response to the question recently posted to info-mac, I
sent one reply but thought that it would make more sense to summarize the
postings on comp.dcom.modems and prepare a report on this modem.

I have clipped responses from the following people on comp.dcom.modems

Subject: [*] Centris Ethernet Report 

Dear All,

A week ago I sent out a request for information about the built-in ethernet
connection in a Centris 650 (as in our College Microstore didn't want me to
use it). I enclose the responses I received for filing as a report.

The consensus is that the inbuilt connector is the thing to use, with the
caveat that Apple's self-terminating transponders may cause problems. One
respondent seems to have had very bad problems with Quadra 700s, cause
unknown.

Many thanks to all those who replied.

Subject: Color LCD Projection Report

About 8 months ago, I requested info about users' experiences with LCD
projection panels.  I got a number of responses, and I was going to post
to sumex, but didn't get a chance to.  Yesterday I got a request from one
of
the Info-Mac readers to send him any info I did get.  It cleared out the
cobwebs, and I realized that there wasn't anything like this currently on
sumex, so I'm posting it now.

However, everything in the technology world changes almost on a daily
basis.
I'm sure there's been many changes, especially with the October rollout of
new Macs, and the never-ending run of 3rd party vendors to introduce new 
peripherals to keep up with Apple's changing line.

Mac Crystal Oscillator Speedup History 2.3                April 1994

There has been a great deal of interest expressed over the net about 
these simple and inexpensive Macintosh modifications that yield 20-
40% speed increases.  Over the last year or so I have been doing a 
fair amount of crystal oscillator swapping/acceleration on Mac's, 
and gathering information from others.  I've made several posts to 
comp.sys.mac.hardware with the bulk of this info and as new 
machines come out, and new concerns surface, I will try to add them 
to this history of the modifications, post them on 
comp.sys.mac.hardware and make them available for anonymous ftp 
on sumex-aim.stanford.edu in /info-mac/info/hdwr.  Included in this 
version is some of the news on the PowerMac's and Marlin Prowell's

Subject: [*] PowerCache performance in LC 

Dear Moderators:

I think the following report on the DayStar PowerCache performance in LC's would 
be a useful addition to the info-mac/reports directory.

The following explanation of how the PowerCache minimizes the effect of the LC's 
16-bit data path was written by Steve Tuttle, the Online Resources Mgr for 
DayStar Digital. I will submit an expanded report to the info-mac archives 
as soon as Steve forwards the results of the benchmark tests on the unenhanced 
LC and IIci, but the results as presented give a good indication of the 
performance difference between a PowerCache-enhanced LC and IIci.

"Altho it would appear intuitive that due to the 16 bit path on the LC you are
going to be forced to run slower, it is not necessarily the case. You see, all
Macs have some sort of delays inherent in their design: The II,IIx,IIcx, &
SE/30 all have 120ns RAM and require 2 wait states to be added to the memory
