That would be a pretty >expensive hobby. actually they were _all_ hardware machines. Belle was the first special- purpose chess machine... Hitech was next, built as a vlsi project at CMU, and finally deep thought which also originated at CMU. Cray Blitz was the only general-purpose computer program of the group, although CB was highly coupled to the Cray architecture, with a vectorized move generator, and a very good parallel search... And you are right, in that except for deep thought, Cray Blitz was stronger than the others...
