The Chess Companion II uses the same Kaare Danielsen program as the Explorer, Concord and Concord II. Apart from colour the casing is identical to the Olympiade.
The Chess Companion II in the pictures is a German Quelle example produced in 1985, but the Companion II was available from 1983 when it sold for £59.95 in the UK, at which price it was good value and sold well.
