As the thread title says. Was wondering if anybody has any documentation on the 200C040 ASIC found in the 89/92+/V200? What does it do? Does it expand the 68k into a 68040? Can it be programmend/exploited, and if so, how?

Hmm I sadly don't know and not many here might know since the 68K scene is pretty much dead, but have you checked http://datamath.org/ ? Maybe they have some extra info or links?
