Despite the horrible hardware limitations, the programmers of that time were able to write many chess engines that were playing pretty well. According to the critics of the time, the best engines were as follows:
- Colossus Chess 4
- ChessMaster 2100
- MyChess 2.0
With great difficulty, I'm doing play to these engines a mini tournament.
No standard (UCI or WinBoard), no possibility to perform automatic matches, but all the moves must be entered manually, first in an engine, then in the other. Nothing PGN. I have to manually enter the moves in a GUI!
it was fun to see how much these engines were playing innocently!
Here is the result of the first challenge, where MyChess has crushed Colossus. Next challange: Sargon-III Vs. ChessMaster-2100...
Time control: 2 minutes per move.
Emulator: Vice (for Commodore-64)
CPU: AMD 8350-FX (overclocked to 5 GHz)
RAM: 16 GBytes
