Does anyone know of any efforts to write modern chess engines for old hardware? (e.g. C64, A2e?)
I'd love to see how a pared-down Stockfish or Leela that could fit in RAM could do rating wise etc.
Surprisingly, I can't seem to find any efforts of people doing this online (to me seems like a fun / informative pursuit).
You can imagine Leela or Stockfish using a compressed NN eval function that can fit in memory (using perhaps low-precision weights) doing pretty well.
Interesting side question: what wins, (reduced) Stockfish on old hardware, or old C64 chess programs (like Colossus, around 1700 rating) on new hardware? I'm guessing the former.
