that's a very nice looking unit, and the docs are a big plus.
I can't speak as to the price, but it looks nicer than the 2 I have. I'll
have to look for my docs.

It’s been a productive two weeks with my pseudo-DEC Heath H-11. I got myself an
Emulex UC07 SCSI card and a SCSI2SD SCSI drive emulator. After a week of
noodling around with why the on-board diagnostics wouldn’t load (stupid LTC
jumper) I was able to confirm that the board and SCSI2SD set

Anyone interested email me.

Well, since it was such an easy job, I took a chance and replaced the
two suspicious 7805 voltage regulators. The terminal works just fine
now!

I'm fairly surprised that the 7805 regulators died, and that they
present this symptom (no horizontal scan) upon their death.
Would like to purchase and restore a big mid-80s VAX. Stupidly passed one up
recently.
Let me know if you have one you'd be willing to part with- also open to trades.
In the Seattle area, but a little too comfortable with arranging freight
shipping...

Bill, surely you have a pile of 1N400x diodes someplace.
Put 6 in series, forward, between the input and supply.
That should ensure it is safe.
If the voltage is higher than 8 volts, it would mean there
isn't enough current to worry about.

Try renewing the thermal compound.
Also, look for any really hot components on the 5V
lines. Tantalums don't always smoke.
A lot of older circuits also used a shunt resistor across
the regulator to share part of the load. These were usually
the square wire wound resisters. These often fail because

That was my first thought, and so I carefully inspected all the pins, but
they all looked good to me. But I suppose it might have been something that
wasn't visually obvious.

I've even heard rumours of parents placing stuff like this into their kids
basements!
(I certainly have some PDP-11's in my daughter's old bedroom! :-)

Hi all,
we have been using two Sun 6800 (each fully equipped with 96GB of RAM
and 24 Sparc III processors 1.2GHz) for many years.
Now they are retired and must leave our machine room to make place
for newer machines.
Anybody out there willing to give them a new home? They are very good
