In 1982 I bought a TRS-80 Level I with 4Kb of RAM.
For this computer I bought a program named MicroChess 1.5. It was very weak but
was able to run in the 4Kb of RAM (actually less than 4Kb was really available
to the program).
The chess engine was probably much smaller than that, because the program had
full graphics and interface. Maybe 2Kb for the chess engine?
However I do not remember if the program was able to play with all the rules of
chess. I'm not sure about en passant capture, threefold repetition and 50 moves
rule.
