(408) We have a new telephone number for those of you with questions! (408) 996-9868 Write it down and keep it ina safe place. It’s IMPORTANT! This is a direct line to our “Answer People,” who are here to help you with APPLE II questions. Since it is a direct line, you won’t have to leave a mes- sage with our PBX operator, or worse yet, have to wait on “hold” while someone else’s questions are answered. If the line is busy when you call, it means “Please call back.” Our question answering ser- vice has been revised in this manner in order to better serve you. It was found with the old system that phone messages computer ince 996-9868 would back up terribly and it took a supreme effort to get them all answered. When we called you back, because of time zone differences, quite often there was no one there to answer. This new system should enable us to help you in a much more efficient manner. We would like your comments, both pro and con, but PLEASE put them in writing so as not to tie the phones up. When should you call Apple? Call us when your local User Group or your Dealer is unable to answer your question, then SHARE our response with them. In this way we will work together to continually improve the depth of technical support available locally. We’re always happy to heip you.... éVi6 bMS LOCAL USER GROUPS .

The first issue of Apple is now ayail- able from your local APPLE dealer. The new magazine will be published three or four times a year, and each issue will have a different theme. The theme of this issue is education, or more specifically, how computers can be used in education. 3 contact 5/the user group newsletter for june 1979 @orpic computer inc. In addition to articles on ed- ucation, the magazine contains our catalog and information on some new apple products. MORE CONTRIBUTED SOFTWARE Volumes 3-5 of the Contri- buted Software Library are now available. These volumes are particularly well documented, so you should have no difficulty using them. EDITORIAL by Roger Cutler, Educational Specialist With the next issue of CON- TACT we begin a regular ‘““EDU- CATOR’S CORNER” column of news and ideas for educators. We know that many schools and teachers around the country have purchased APPLE II’s. We hope, through this column, to let you know what other educators are doing with their APPLES. Many publications have asked us to locate interesting projects and articles written by educators. Let us hear from you, so that we may pass along the news to others. Microcomputers represent a new and exciting medium for teaching and learning. During the next year there is going to be an explosion of educational soft- ware and courseware. We at Apple want to support and help coordinate these efforts. We need to know what you are doing and what your needs are. As many of you know, the Minnesota Educational Comput- ing Consortium (MECC) has selected the APPLE II micro- computer for the Minnesota School system. It is converting many of its educational programs to run on the APPLE II, often with graphics, color and audio enhancements. Watch this new column for news of how you can obtain these programs. Another interesting project is underway at the Lawrence Hall of Science at Berkeley, Cali- fornia. In a special outreach project, the Hall is visiting schools in the San Francisco Bay Area with a van full of APPLE Il’s, bringing classes in program- ming to students right in their classroom. Joyce Hakansson, director of the project, reports an enthusiastic response wher- ever the ‘‘Apple Cart” goes. Finally, we have plans at Apple to support education in many ways. You can expect to hear about them in the EDU- CATOR’S CORNER. OUT OF THE MIST.... Hey! I needed that... Well, here are some of the much praised subroutine Calls for the APPLE. This started out to be quite a project as most of the more obscure calls are buried deep in the heads of people back in Engineering. Then, just as we really got to digging, we re- ceived a copy of the ABACUS (Apple Bay Area Computer Users Society) newsletter. These guys have already done all the work! So, if what you need is not here, write to ABACUS at the follow- ing address for a copy of their list. ABACUS 2850 Jennifer Drive Castro Valley, CA 94546 It seems from the number of questions we get that most peo- ple consider Peeks, Pokes, and Calls to be somewhat magic. We’ve even had people ask for the Poke that would increase the capacity of their DISK II’s! In light of this, maybe a short explanation of terms is necessary. PEEK~—This command allows you (or your program) to examine a specific byte of memory. It will always re- turn a decimal number in the range of ‘0” to “255”’. The address to be examined is always specified in DECI- MAL too. (This means that “PRINT PEEK (768)” will display the contents of address $300.) POKE-Sort of the partner of PEEK. This command stuffs a specified decimal number into an address. ““POKE 768,255” will change the contents of address 768 ($300) TO 255 ($FF). This command is useful for plac- ing a machine language sub- routine into memory. (See the TONE ROUTINE on page 45 of your “RED REF- ERENCE MANUAL”. CALL—This command runs a subroutine already in ROM (Read Only Memory) ora routine “POKED” into RAM (Random Access Memory) by your program. Again, see the TONE ROUTINE in your manual. So, without further delay, let’s plunge into the interesting world of PEEK, POKE, and CALL... NOTE: THE POINTERS 60-63 SPECIFY THE BEGINNING.

How many times have you started merrily programming in Integer Basic only to find out that you should have been using Applesoft? Well, for you Disk II owners, here’s a trick that can save you a lot of typing. Enter this line anywhere you have room in your program. In the example we’ve used line “Q”, but this could be any available line number. (For this example, the symbol “@”’ means “Control D’’.) @ PRINT “@OPEN X”: POKE 33,338 PRINT “@WRITE X”: LIST: PRINT “@CLOSE”: END When this line’s entered, type the command “RUN”’ and press “RETURN’’. Your program will now open a file called ‘‘X”’ and list itself into that file. When that operation is complete, get into Applesoft with the “FP” com- mand and EXECute the file. Viola! Your program is now in Applesoft just as though you had entered it from the keyboard! Back to Black and White If you are one of the pio- neers that bought your APPLE before the days of the color killer modification (S/N 6000+), and you use a color TV asa monitor, then this hardware modification may be of interest to you. First add two parts, a 2N3904 transistor (or equiva- lent) and a 1.5K resistor, to the breadboard section of your Apple as shown in figure 1. The transistor base and one end of the resistor should be tied together. Then wire the other g TOP VIEW Coeoedee taeditne a — COCRCEGERECEE GEO OEE ono GRRCCERCEC ERROR GOR e eee end of the resistor to IC F14- pin 4, wire the transistor emitter to ground. The capacitor next to the edge on the corner will do as a ground. To test the final product, put your APPLE back together and turn it on; go into BASIC, type GR, then type TEXT. The screen should go from color to black and white. IMPORTANT! Please wait until your APPLE is a year old before making this modification as it will void your warranty.
