ST-Computer PD - Public Domain

ST-Computer, also known as "series S", is one of the biggest public domain series for the Atari ST at 1000 disks. Originally published from 1986 to 1996, the series showed the growing sophistication of Atari ST software and the slow change towards more multitasking-friendly and cleanly written applications.

  • Zaptastic
    Remember Jeff Minter's Anticipal on the C64? Well this is basically it on the ST! It's essentially a madcap shoot 'em up in which your aim is to eliminate everything that moves in all 64 rooms within the set time limit. It's odd, it's weird but it's great fun too.

  • Puzzle 97
    A jigsaw puzzle game which runs in any resolution. Load up an IMG file (its colour depth must not exceed that of the current resolution) and select whether you want the puzzle made up from large, medium or small sized pieces. The actual number of pieces varies dependent on the size of the image. You are then presented with a conventional jigsaw puzzle on screen in a scrollable GEM window. Unlike the real life scenario, all pieces are the right way up. You can place pieces directly onto the playing area or build up sections of the puzzle independently of each other then move them into place on the main puzzle. Unfortunately the program and docs are in German and Polish but it can be picked up in five minutes as everyone knows how to make up a jigsaw puzzle! This is the best ever attempt at such a program. Several example files are supplied on disk and you can save semi-completed puzzles at any time and resume them at a later date. On an STE, TT or Falcon, you even get stereo sound effects! Runs fine on an FM too. If you don't have NVDI installed, you need to run the supplied ENHANCER program, otherwise PUZZLE97 won't work.
