Netra's are sun4u, unless they're labeling various US II processors
differently, which I doubt. (sun4u starts with the Ultra series.)
US III-based machines are probably also sun4u.
sun4 are all sparc-based machines.
I don't know what I was smoking when I said sun4ms were m68k. (See
below.)

Weird. Must be different Sparc revision levels, if it's actually the
main processor causing the problems. (Could also just be flakiness
in the bus controller, no?)

Sure, but they're no E3500 (you know, the one with the Cray
backplane). ;^>

I was wrong, obviously. :^>
sun2s and sun3s are m68k.
All sun4s are sparc of some sort.

Hrm. That's neat. :^> Anyhow, I'm pretty sure I was thinking of
sun3 stuff when I even mentioned m68k OR similarity in serial
chipsets between suns and macs. So it's probably nothing you've
got.

Be interesting to see.
What's the vendor name on the chipset on the various machines you
have got? (All my sun4cs are off right now, and Solaris doesn't so
much report things like that.)
