Only the Alice corrupted video output bug doesn't crash the computer. In fact, it rarely even corrupts the viewable chip ram! It just causes all sorts of visual effects to be displayed. If you try to snapshot the screen while it's showing this effect, the screenshot looks normal.
Actually it never corrupts chip memory.
That sounds like the problem where if there were any colours onscreen that were full-white, ie 255,255,255, the gfx would get corrupted after a few minutes -- my brother's 1200 had this problem, but mine didn't.
Now THAT'S one I've never heard of! Quite an odd solution, too! What little I know about the real electronics of how computers work would lead me to believe that is an artifact of one of the 'timing errors' that are discussed for the 1D3,1D4,2B motherboards.
This is not the timer problem, but the Alice pb discussed above. There are even patches in aminet that patch all 255,255,255 colours to 254,254,254 to workaround the problem.
