Ummm. Pretty pointed "PS", Frank.

Isn't that caller's question best answered by KLE, rather than in your own Q&A
file?  Personally, I don't think that either company should upload info about
the other's machine (yet). Even well-meaning answers can be misleading, being
based on changing specifications. So I believe that each company should talk
ONLY about what it knows right now: its own hardware.

I suspect that _both_ companies would benefit from such a policy at this time.
Of course, if each company wishes to release me to talk about the status of
_all_ their pending plans, I'd be than happy to indulge in some fair slicing
through of the hype on both sides, myself .

In any case, the info I have is this: The MM/1 normally would use a 16-bit bus
with 16-bit peripherals (those can also be used on the 32-bit bus, natch).

There will be a shared-RAM adapter for the two main MM/1 cards to plug into a
larger 32-bit bus... allowing multiple MM/1s to coexist with a 68030, much in
the same way that multiple TC9s coexist with your K-Bus 68030. So the MM/1
isn't "discarded". I guess it would primarily be used as an intelligent
gfx/sound/io device once a 68030 is added.

New Q's: What happens to a person's TC70 when he upgrades to a 68030 on the
K-bus? And what calculations were used to show a 68030 using 16-bit RAM slowed
only 5% over using 32-bit RAM? Or was that only when accessing peripherals?
