In the past few years, we have covered plenty of neat chess and checkers computers here. The SciSys Electronic Trio lets you play both of those games. It also has a Tic Tac Toe mode. Introduced in 1986, this chess computer has a beg sensory board and shows the moves with LEDs. It has 3 compartments that let you store the pieces.
The SciSys Electronic Trio Computer has 8 levels but higher levels take more time per move. You can switch mode with the push of a button. You can find it on eBay at the time of this writing.
