Stronger early chess computers. This is the Allegro 4 by Novag from1989, build in Hong Kong. Full working condition with the original instruction manual. Played a test game (lost) and it works fine, uses 6 AA batteries (not included). It is in good condition with small signs of use. Nice grey and black pieces. The computer measures ca 25 x 25 cm or 10 x 101 inches. See the attached video on Kasparov in 1988.
