Mephisto MM V,
a dedicated chess computer module for Mephisto module systems by Hegener & Glaser launched in 1990 as successor of the Mephisto MM IV with the same hardware. Ed Schröder's Rebel program ran on a 65C02 CMOS processor in 32 KiB ROM with 8 KiB RAM at 5 MHz, but gained 70 Elo over its predecessor and was tactically much stronger since it could solve deep combinations, while only doing 500-600 nodes per second [1], due to searching all check giving moves in the first at least two plies of the quiescence search, and even deeper if check evasion had only one or two legal moves [2].
