Developer’s Diskette

(Recommended for advanced programmers/Written in BASIC and machine language)

This diskette contains preliminary versions of a few APX utilities, together with some demonstration and miscellaneous routines. Many of the programs contain rough spots. Because we’re offering the diskette unsupported and because the user manual is very sketchy, you’re pretty much on your own. All but the most advanced programmers will have difficulty understanding the contents of this diskette. Software developers who have attended Atari’s development seminars already have the routines on this diskette.

The contents of this diskette are subject to change without notice.


Some of these programs contain significant bugs. The user manual is POOR.


  • ATARI 825 80-Column Printer
  • One ATARI Joystick Controller
  • Assembler Editor Cartridge
