Re: [stella] Video/Computer Chess

[David <davidgalloway@xxxxxxxxxxxxxx>]

Not what you are looking for but related is the source code and a little 
back story to Micro Chess for the Kim-1
It's only 1K of ROM but uses more RAM.
http://www.floodgap.com/retrobits/ckb/secret/microchess.html

I looked it over and it uses about 170 bytes of RAM in zero page and 
appears to make ample use of the separate 256 byte stack to do backtracking.

Running with the limited RAM, the chess implementation for the 2600 must 
be fascinating!

(Interesting side note: found Larry Wagner's (original author Video 
Chess logic) resume on the net. http://pctvnet.com/dsp/  In his resume 
he mentions the chess game as 6K. Saw a 6K version on the Atari Protos 
site but the shipped version was 4K)
