In the past few years, we have covered plenty of advanced chess computers, including the DGT Centaur, Square Off, and Chessnut EVO. Older chess computers may not be as strong but can still give you a good game. Take the Mephisto Milano for instance: it is an electronic chess computer form 1991 with an estimated rating of 2100 ELO. It has a tiny display to show the moves. It also shows the moves with LED lights.
The Mephisto Milano has a 5 MHz processor and 8Kb RAM. It has a press sensory board. The design is almost identical to the Mephisto Milano pro but the display is a tad bit smaller. This chessboard has various levels for you to choose from. It has opening modes, including opening training. It is rare but you may be able to find it on eBay.
