Murray Arnow/Call -A.P.P.L.E. staff writerJune 1983 / PP 49-52 Apple CP/M is probably the least documented of the operating systems available to Apple users. With this in mind, I hope to share some of the information I have been able to gather on the 2-80 Soft Card and the associated Microsoft implementation of CP/M. Before I begin, let me urge the reader to refer to the series of articles by Gregg Tibbetts in Softalk magazine titled SoftCard Symposium. The latter…

WERE off to greet spring-time and the West Coast Computer Faire with a special 128 page issue, our largest to date. Lest we forget, the dates for the big show of the year IS March 18-20 at Brooks Hall, In San Francisco’s civic center. Hope to see you there, and at the Anaheim Applefest In April. From time to time in Call-A.P.P.L.E, we often feature assembly language programs which use Applesoft’s powerful ampersand (&) command, which has the capability of…

IAC DOS 3.3 and CP/M Hybrid Disk This disk is a hybrid which is in part a CP/M type of disk and in part a DOS 3.3 type of disk. It contains files of both types on it, but it does not (yet) bear an operating system. Like IAC Disk #20 (available from the IAC for $8.00), this disk is a special format designed to assist Apple users whose machines are equipped for more than just the DOS 3.3 operating…

HERE It IS, what you have all been waiting for … the Apple II ReVISion e. Our lead story Reving Up the Rev e by Call-A.P.P.L.E. staff writers Clif Howard and Art Schumer IS a giant cooperative effort between the authors, Apple Computer, Inc. and ourselves. You can read the full-featured review of a full-featured machine starting on Page 9. And don’t be concerned about any in- compatibilities With existing software; they will be few and far between. The Identification…

A new year is upon us, another 12 issues of Call-A.P.P.L.E. We would like to request again our readers Input. What are your preferences and dislikes. Take time, if the thought appeals to you, to photocopy the contents page and rate the stories. We’re interested also in how you use your Apple, whether or not you write your own programs or plan to. Comments should be addressed to the Editorial Office at the address shown on page 2, and should…

A Call-A.P.P.L.E. Techniqueby Mat DavisCall-A.P.P.L.E. Magazine October 1982 PP17 One of the Apple’s strongest points is its ability to use multiple operating systems such as DOS 3.3 and Pascal. For someone who uses both of these operating systems, there are times when it would be convenient to have disks that both Pascal and DOS could use. Such a disk would be useful for individual users who are trading programs or for user groups who want to have some Pascal programs…

by Ted Perry Call-A.P.P.L.E. MagazineJuly / August 1979 When I was asked to help put together a CAI (Computer Assisted Instruction) subgroup, I naively said I would. The demands of correspondence quickly overran my capabilities to respond and the initial influx of programs overran my ability to document. Now with the help of a group of dedicated computer aficionados, the correspondence is under control and the documentation is in process. In this first article I would like to describe the…

The APPLE-II color graphics hardware will display a 40H by 48V grid, each position of which may be anyone of 16 colors. The actual screen data is stored in 1 K bytes of system memory, normally locations $400 to $7FF.(A dual page mode allows the user to alternatively display locations $800 to $BFF). Color displays are generated by executing programs which modify the “screen memory.” For example, storing zeroes throughout locations $400 to $7FF will yield an all-black display while…

The following recipe will save you loading time on your Applesoft programs. 1. Load Applesoft 2. Do not “RUN” it. 3. Using the DEL command, delete lines 0,940, inclusiv. 4. Enter this line: 950 POKE 18,255 This will give you a preset version of Option 1, Applesoft graphics mode. 5. “SAVE” this at the beginning of a blank cassette and follow it with saves of programs written in Option 1. For Option 2, do the same except make line 950…

The Apple II paddle I/O Port is immediately available to connect an RS232 type. serial mode printer. Tom Geer, of the Empire Electronics store in Burien is probably the first person in the area to have a TTY up and running.  If you ask, Tom would probably be glad to give you some hints on how to proceed. There is a simple machine language program in the revised Apple II manual to enable a printer. Empire has ordered a number…

Users can dress up their Apple II program with a simple tone subroutine to direct attention to error messages and other items of importance. From BASIC, you simply need a Call -1050 ($FBE6).  This will produce a 1·000 cycle tone to be emitted from your computer.
