[comp.sys.mac] Bus question

johnston@dalcsug.UUCP (Bruce Johnston) (02/16/89)

Howdy there all you mac people.
Living up here in the warm and sunny north causes the news to travel
a lot slower.(you know, people would rather be at the beach, that sort of
thing). Anyway this question may have been asked before, but I can't
remember, so here goes.....

I was wondering what bus system the rumored 3-slot Mac IIx (maybe coming
out in March I think....) would be using. Will it use the NuBus slots like
the Mac II and company or will it be sporting the New Bus of the SE/30.
Anyone heard anything?

Oh yeah, what are the differences between these two buses and which one is
better.

If this has been asked before then just ignore my ramblings.

Thanx in advance.

I have read that the new 3-slot macIIx (I think they are calling it
the Mac IIcx.) will use the NuBus. The SE/30 (like the SE) doesn't really
have a "bus" other than simply an extension of the microprocessor
bus out to a connector. 
  The NuBus is in many ways "better" than the "buses" on the SEs.
The NuBus is an industry standard, and cards that are made for one Nubus
machine (regardless of microprocessor used) should be able to be plugged
into any other machine with a Nubus bus.
