This game was never ported outside its original computer, the Apple II, therefore, its graphics are somewhat reminiscent of happier times, when graphics didn't have nothing to do with the quality of a game. In this game, in short, you find yourself in a subterranean city populated by robots, which prevent your going where you please. You can't move at will, but your personnal robots (which you find at the beginning) won't be detected; therefore, you need to cable them, using in/outputs, solderpen, logical gates, circuits and microchips, to do the actions you can't yourself achieve. This is not only a game, but a complete cursus in logics (AND, OR, NAND, etc...). Needless to say this is not easy, but it remains to this day one of the best puzzles ever. You can find the game here, and you'll need an Apple II emulator to run it. I recommand AppleWin for simplicity, although it doesn't work with my video card(TnT2). Else, I also have uploaded ApplePC, although it runs to fast. For this problem, and others concerning old games and speed, I have uploaded MoSlo.
