Frankly, from your description I'd be wondering whether it *is* time to think about a 68020 or 030. Your plans are taking the 68000 farther and farther from direct control of the bus; it doesn't sound like it would be lots harder to just switch to one of the better processors. They are capable of running on the narrower bus, and apart from being faster in various other ways, have built-in caches. -- Apollo @ 8yrs: one small step.| Henry Spencer at U of Toronto Zoology Space station @ 8yrs: .| uunet!attcan!utzoo!henry henry@zoo.toronto.edu
