Very interesting: Modena was launched in 1992, and I'm guessing it must be close to the end of the 8-bit 6502 era in dedicated chess computers. Am I right?

Regarding the position (which follows white's move 37 on the pgn), I did not spot the key move: however, the pgn board's analysis mode (click the board's E8 square) did quickly find all the right moves up to move 40, where it prefers Rd6 over Qe3: this choice still wins next go.

Nice position, and kudos to the pgn analysis board (which runs a small program in JavaScript in your browser)! king

Yes, I think you may be right. The Modena was Frans Morsch program.

Kathleen Spracklen said that "short branching" made the 6502 a good choice of CPU in comparison with its main rivals (the Z80 and the 8088) - link.

Reliving the past when everything was new, back to childhood so to say.
