 SciSys Chess Partner 2000, also sold by Novag with the same name.
 It's probably the last SciSys / Novag collaboration.

+Entering moves is not as friendly as newer sensory games. The player is expected
+to press ENTER after their own move, but if they (accidentally) press it after
+doing the computer's move, the computer takes your turn.
+
+Capturing pieces is also unintuitive, having to press the destination square twice.
+
 Hardware notes:
 - 3850PK CPU at ~2.77MHz(averaged), 3853PK memory interface
 - 4KB ROM, 256 bytes RAM(2*2111N)
 - 4-digit 7seg panel, sensory chessboard

 3850 is officially rated 2MHz, and even the CP2000 manual says it runs at 2MHz,
-but tests show that the chesscomputer runs at a much higher speed. Three individual
-CP2000 were measured, by timing move calculation, and one recording to verify
-beeper pitch and display blinking rate. Real CP2000 CPU frequency is in the
-2.63MHz to 2.91MHz range.
