Actually, you may want to set the disk to ID 3. SunOS does this weird
swapping of ID 0 and ID 3. Somebody posted the historical reason a while
back to comp.sys.sun.hardware, but I believe it had to to with 3 being the
likely address of another sort of device.

Well, the last one for the Sun3 was 4.1.1. With a 3/50, you may actually
want to stay with an older OS, say 3.5.

One thing you may want to find a a 68882 math co-processor chip for it.
IIRC, they were not standard, but I do recall bumping into a couple of
things that *really* wanted it (X11 under Mach, for instance).
