[comp.os.mach] Mach 2.5 on Sun 3/80

gorlick@Aero.org (Michael Gorlick) (06/04/91)

I have been given to understand that there are significant
architectural differences between the Sun 3/80 (based on the mc68030)
and the other mc680xx based Sun products.  That being the case,
does Mach 2.5 run on the Sun 3/80?  Thanks in advance.

Mach 2.5 (at least as released by CMU) does not run on Sun 3's with
68030 processors (including the 3/80).  The MMU is sufficiently different
that it won't work.  That's why I'm running a blindingly fast 3/60 :-(
