Summary: What about the new '030 Card?


[Don't have any reference for the '030 yet]

Since CSA has an '030 card coming out, (which sounds great), does anyone
know if the '030 boots up in a manner compatible with the '020. What I'm
wondering about, is the MMU on the Commodore 68020 card going to constrain the
internals of Exec/Dos to not use the MMU on the '030. I doubt if it is
compatible, but hopefully it does a subset, at least. It sounds like another
round of, well you can upgrade to the new CPU, but you can't use any of
the features of it. You know, turning off caches, etc., seems to be
mandatory with the '020. And the '020 really only speeds up with 32-bit
memory, as well. I suppose the rumored(:-) Unix from Commodore probably won't
run on an '030, because of the MMU issue. I assume that if CSA is releasing an
'030 card, the current ExecDos runs on it.

I hope that some of the lag time until the next OS release is used to look
at these issues. I think everyone wants over time to upgrade to at least the
'020, then the '030, [of course, the chips have to go down to $5 each :-)] so
let's try to make the path less bumpy!

I hope this is a change of pace from piracy/virus/mtask flaming!
