Not to many >people own one. 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. >Belle ran on a LSI 11/23 mainframe combined with a special chess processor and >searched at about 110Kns. I believe this machine is in the smithsonian. 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.
