Yes.  I would guess or suspect that the suppression (if not from
mere boredom by Goble) had more to do with the charcoal spectacular
than from toppling dual 780s.

Incidentally, I think the first multiprocessor Unix was
done at the Naval Postgraduate School in Monterey for an MS
project; this was a PDP-11.

It would be appreciated if it were possible for anyone to scan

Since this is a rather unusual crowd - does anyone have the

a few months ago i found a binary of the plan9 vax compiler when
looking for something in the dump, but no source. there was one because
the original fileserver was a vax750 with a worm drive and connections
to gnots (terminals) were serial. there's a microvax in the storage cage
still.

Re: [9fans] Mt. Xinu

probably not enough memory for a workable plan9.
my MicroVAX is fully stocked (i think) - a full 9 MB
of memory.  this is fine for Research Unix (V10) but
a cheap PC is better for plan9.

Actually, the loon in both cases is George H. Goble, who still works here

AFAICT, it's just BSD with NFS bolted on.  We're still running it on a

A stalled jet.  We never took down the power grid after a restart,  
but came close a couple of times.  (We didn't have staged spin-up for  
the drives ...)

Nah, we dumped the big disk farm (three canaries and an eagle) onto  
QIC 120 MB carts.  On accounta that farm was hanging off the Sun  
3/160.  The 785 with the SI only spoke to lowly RA81s.  A lot of

no. they were independent 780s, except for the goofy-net between
them.

i don't miss the stuff at all. quotacheck took 2 hours on a grand total
of 1.5 G of disk. (assuming you didn't need to plug a terminal into the
back of one of them and sacrifice a few cats to the compter gods.)

oh, and i just remembered. the weekly backup took about 8 hrs for 1.5G
onto 9 track. we did have a VHS-tape based backup that was never completely

Was this related to the first 2-way 78x that (I think) was built at  
Goergia Tech?  (It's been a long time since I read the paper about  
this.)  (I'm thinking about the same loons who start their BBQ with

Oh yah?  My 785 had a paper console (LA34), 24 MB of memory(!), and  
also took up close to 27 feet of floor space :-)  (We had Ethernet,  
too, but I never measured the size of the card.)

We had to halt the microcode floppy IPL to poke a register on the TU 
(?)x controller to put our (not DEC approved or supported) SI9000 tri- 
density tape drive into the correct density in order to read the  
install/upgrade tapes ;-)

Re: [9fans] Mt. Xinu

[quanstro]

they supported a special connection between two vaxen
which would let them share dec raXX 80mb disks under
special circumstances. i think we were able to share the 
mag tape, too.

those suckers had paper consoles, 4 and 8mb of memory
and the largest ethernet card i've ver seen --  whole 9 yards.

the kernel had to be rebuilt to change boot devices!
