Sb: #32 bit bus?

Kev,

The MM1 ads state that it has an 32 bit expansion bus. However the 68070 in the
MM1 is 16 bits and you are instructed to discard the MM1 when you move to the
32 bit bus. Several callers asked about this thinking that the MM1 could be
expanded on this 32 bit bus. Unless my math is wrong or I've become very stupid
you can't run a 16 bit CPU on a 32 bit bus. If you could it would serve no
purpose whatsoever. Before I add this to my next QnA upload I want to make sure
I'm not missing anything.

Can you really expand the MM1 with a 32 bit bus and if so how? Is this just ad
hype?

Frank

PS. Remember the old SWTPC ads with a 25 Amp bridge rectifier? Used to get
Gimix really ticked because they had a 25 Amp power supply and the SWTPC only
had a 8 Amp power supply. Yet the SWTPC ads said it had a 25 Amp bridge
rectifier with no mention of capacity of the supply itself.

Sounds familiar.
