Part of the fun of the Oldies is finding out what is actually inside them rather than what people think is inside them. I'm discovering that. :) And CXG did some weird things with mixing-and-matching, for sure. It would be nice to know what is in the machine of the guy who played those games at the...

Thank you! I appreciate it and do hope you got the thing back together. It still leaves the mystery of the irreproducible games (and the wiki). This document suggests there were two versions, one in 1982 and another in 1984, but isn't sure. Maybe the processor was the difference...? It just makes no...

CXG Advanced Portachess: What processor is in it??
Schachcomputer Wiki says Hitachi HD44801. Simple, right? Well, the spec sheet at the end of this file indicates it has the same chip as the CXG-002, which is a HD44840 (I know because I have one), and a different chip than the CXG-001 (which in fact has a HD44801). So which is right? The wiki or th...

Since the topic of CXG has come up, there's something I've been wondering. It's not about the best of the CXG computers but possibly the worst of them: the original Sensor Computachess (CXG-001) There is bug in the software for its immediate successor, the CXG Computachess II (CXG-002) (my very firs...

Let us know what happens!BenRedic wrote: Request sent. Fingers crossed.
It looks like Chess 4.6 is probably the latest anyone will ever get, in trying to resurrect these programs. Once BELLE came around, customized hardware became a thing. Of course, BELLE was apparently donated to the Smithsonian, so...

I see they say that the program they use is 2.11 BSD chess. I did some looking around, and found this: https://sourceforge.net/projects/bsd42/?source=typ_redirect Does anybody have any idea who programmed this one? Could this be related to the Thompson program mentioned earlier, or is this somethin...

You might be aware of this already, but there are many downloadable emulators of PDP systems, which were the machines that a lot of 60s-70s programs ran on. Just google PDP emulators and discover. A while ago I tried one myself, because I happened to be interested in the very same thing as you: the ...
