Hmmm...  similar enough to m"

Sheeeit.    I suppose when I have the time I should try netbsd (which I
think I still have an NFSroot for) or SunOS (eep.  never even tried that
install.  terrifies me).  and see what kind of perf cam come out of that.
Of course, that nagging thing called my paying job may keep me from doing
so any time remotely soon. :)

Yeehaw.  :)   Sounds like a blast.  I've not even been able to look at
most of the stuff like VME ethernet due to my inablity to find a VME sun3
close enough to me to pick up, or having the throwaway cash to ship one
(though I drool every time I see the numbers 3/260 come across the
monitor).  :)   the ie drivers should be easy to rip...   What was the
sun2 scsi controller?
