- this is -really- strange. i was under the impression that all 68k
- processors after the '020 were 32 bit all the way 'round. can someone
- post a 'family tree' of the 68k series & what is what? going to
- 24/16 for a 32 bit processor sounds like something Intel would do,
- not Motorola.
-
- i realize that Motorola doesn't have a lot to do with the bus design,
- but it seems to me that trying to fit a 32 bit external processor
- on a 24/16 bus would be a lot more hairy than just making it 32 bits
- in the first place.
