They wanted a Cray, but i don't think they ever got one, and had to run on a
lesser machine. I am pretty sure it was written in Fortran (probably Fortran 66
or something similar). If so, it shouldn't be all that difficult to port it to a
modern PC. All the other programs you mention are either assembler language, or
special hardware, so they would be very hard to get going now.

Mostly correct. Except that calling an LSI 11/23 a mainframe would make anyone
who has seen one laugh. And anyone who has actually used one would laugh even
louder. LSI 11/23 was a microcomputer, and a very old and slow one at that.

>Chess 4.9 is a previous version of Nuchess.
Some of the same people were involved, and the programming ideas were mostly
similar, but Nuchess was a complete rewrite. Chess 4.9 was CDC6600 assembler.
Nuchess was Fortran.
