Chess 4.9 was CDC6600 assembler. >Nuchess was Fortran. Not exactly. At every ACM event you saw "nuchess" playing in, it was playing on a Cray. I was using a cray at the time and helped them make arrangements to use one in the same lab I was getting time from... I don't recall _any_ ACM event (NACCC or WCCC) they played in using anything but a Cray (nuchess program). Bob
