This is off the top of my head, but here goes:
Mule (an all-time classic!), Forbidden Forest, GI Joe (esp. the PvP), Hitchhiker?s Guide to The Galaxy (text-only, co-written with Douglas Adams, funny as the book), Way of The Exploding Fist, Paradroid, Beach-head, Summer Games, Archon (another all-time classic), Jumpman, Jumpman Jr., Raid Over Moscow, Spy Vs. Spy (the first and the best), Seven Cities of Gold, Elite (still an all-time favorite), Commando (the remixed music is an enduring classic), Bop & Wrestle, Gunship, Summer Games II, Winter Games, California Games, Archon II: Adept, Silent Service, The Last Ninja (some of my favorite game music ever), Pool of Radiance (best on the C=64), Pirates!, International (World) Karate Champion, Airborne Ranger, Platoon?
Were it not for Shogun: Total War, I?d probably be playing a few of these myself-ah, the good old days?
