Schachmattnüj kompjuter made in russian federation Very nice! Reminds me of some devices from gdr produced by robotron... EC1834 had same cpu. Sometimes there was even Siemens 8086 inside, despite of trade embargo...

It is said, the WM86 (BM86) stands for "we made 86"

Do you know the retail price in rouble?

Cheers,
Andreas
