Well, 12 years ago I build my own "eboard" that communicates with engines like Stockfish, LC0, etcetera using the UCI protocol. I now want to be able to use my eboard with the old chess computers that are availble in MameChess. You can already use these with Arena using UCI to communicate moves and analysis back and forth. I just need to figure out a way to spit this out over a USB/Com port to my own eboard. I thought ChessLab was using UCI since it interfaces with eboards and the old chess computers (see MameChess 2020 Mysticum Touch).
