Our local chapter of ACM (association of COmputer Machinery, a
bunch of cs geeks mostly :)) has got ahold of a BBN Butterfly,
which contains 32 motorola 68k processors... (68020 I believe)
Is running NetBSD on this thing a viable option? I know it's
been ported to the 68k architecture... but will it run on a 32
processor machine?
I could be wrong -- it's happened before ;> -- but I'm pretty certain that
NetBSD requires a 68030. The only free *n*x I know of for 680x0, x<3 is
MiNT (originally developed for Atari, also exists for Mac).
You are. NetBSD runs fine on Amiga machines with CPU 68020 + MMU 68851
+ FPU 68881. You should check whether one, or all, of the cpu's are
equipped with at least the MMU chip.
As for multiprocessor machines, ahem... we aren't multiprocessor clean
at the moment, although the things to do have been partially
identified and started. A NetBSD port would, at the moment, need to
switch off 31 of the CPUs :-)
Do you have enough hardware details (e.g., memory map, i/o device
information, interupt routing etc)?
