these algorithms I read/study in computer classes discussed here!

	The 68851 (PMMU) car would still be neat...

	Is "10" a "couple"? It seems that the commonly accepted value is
at least a million GSes out of over 5 million Apple //s total.

	A great UNIX chip? Please explain in mail...

	Well, the person who is going to hopefully make the 68851 card
has also compiled part of UNIX on a GS and I believe it worked... (although
I honestly don't know how they could tell if they'd not written the low-level
GS specific routines necessary).

	Anyway, you think the GS with the 25 megahertz 65816 and a 68851
wouldn't have the "Get up and go" to support UNIX?
