Jetman [ Full instructions for Jetman are printed by the game itself. What these don't mention is that, because of the way in which the program uses IN to read the key- board, it can only be played on Issue 3 Spectrums. Note that this is the opposite of the normal case with such programs; usually, they can only be used on Issue 1 or 2 machines, and will not work on Issue 3s. Also, Ultimate are veritably quaking in their boots. ]
