...my favourite, a Fidelity A/S Elite Glasgow Chess Challenger...
One of the advantages of playing against vintage chess computers is that you don't have to artificially dumb them down to beat them once in a while. ... Sure, Stockfish will clobber you, but you can learn something from it.
I still own the one I learned chess with forty years ago, the Chess Challenger 7 [the first model that really hit the big time on markets around the world].
Gorgeous wooden dedicated chess computer (DCC) you have there. Is it just me or are the pieces quite tall with respect to the surface area ratio of the board?
With the current strength of chess engines, I do not know of anyone who uses them to get the satisfaction of defeating an opponent - that's what chess.com is for. The strength of DCCs now is for OTB analysis; hence, you learn "something" from them. I read that the SquareOff machine uses Stockfish 8 and the soon-to-be-released Millennium King Performance wooden computer uses the updated Johan de Koning's program - remember the Tasc R30?

I was gifted a vintage Fidelity Chess Challenger 3 - the unit prior to the sensory board. It didn't age well. Fidelity learned a lot with manufacturing DCCs with that model.
However, I have to ask if people still play with anti-computer moves against chess engines. Does that still work?
I read that the SquareOff machine interfaces with chess.com. Something that DGT is still struggling with. That’s another Plus for the new physical chess computers!
