by Val J. Golding Call-A.P.P.L.E. Magazine March 1983 PP81 CP/MUFFIN was a rush job. We had a story submitted to us on Wordstar on a CP/M formatted diskette. Fortunately for us, we had just published a story in the December Call -A.P.PL.E. by Art Messler, which pretty well explained the structure of a CP/M directory. As it turned out, the clues in that story were sufficient to start us on the right path. We were working in the dark, not…
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 Thomas G. WilliamsCall -A.P.P.LE. July 1982 PP79 THE Symbol Symon symbolic debugger is a major improvement over the capability included in the Apple ][ monitor. Unfortunately, it does not know about the Big Mac.LC assembler and thus can not save or use the symbol table produced by Big Mac.LC. Symbol Symon can be used without a symbol table, but you lose the capability to refer to locations by name instead of address. Fortunately, the Big Mac.LC symbol table is…
by Ted Perry Call-A.P.P.L.E. MagazineJanuary 1980 V03N01 PP35-36 This is a progress report on the project reported upon in the July/August issue of CALL-A.P.P.L,E. As you probably recall from the original article, the Kyde Tyme Project and the CHIP Project arc computer assisted instruction grants funded by Title IV-C to develop computer assisted instruction on the Apple Microcomputer. Our tasks arc to develop a CAI author Language for the microcomputer; add graphics to the format that in the past used…
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…

By Bob Huelsdonk Some protocol is a must if you use a printer with greater than 40 columns with your Apple. This comes about because it tries to write beyond the screen area and into the variables area in Integer BASIC or into the operating system in Applesoft. The following fix will help prevent this problem: Start your printer driver routine with a JSR FC58. This will home the cursor and clear the screen. Do not return to the screen…
