Earlier chess computers by Saitek and endorsed by Kasparov himself. This is the type Conquistador from 1988 with a special display, showing the time for each player like a chess clock could. Not the strongest chess computer but it has many options for learning. Fully working condition with all the paperwork. Played a test game (lost) and it works fine, uses 4 larger type batteries (not included), also tested on a 9V power converter (not included). It is in used condition with clear signs of signs of use (no cracks) on the computer as well as on the pieces (silver bishop missing small ball). The computer measures 42 cm or 17 inches wide. See the attached video on Kasparov in 1988.
