One of my 2100's has developed a problem. It was working fine for some time,
but was only powered up occasionally. The problem started when I ran some
burn-in diags over several days. The machine started acting funny, and when
I powered it off and back on, there's no front panel display at all - no
lights. However, all the fans come up, one of the internal boards that has
an on-board led is lit, and I checked all the outputs of the power supply
and they're just peachy. I moved every single card (including the front
panel) from the bad system to another system and it then runs fine so I know
it's not any cards. I suspect the power supply, but as I said all the
outputs appear good. Gawd I hope nothing happened to that wire-wrap
backplane.
Can anyone offer some advice? I'm starting to pour over the schematics on
the power supply - wondering if something is amis with the poweron or
powergood signal perhaps but I don't know much about it.
Any tips most appreciated!

I got a couple of "free" VT320 terminals with a system I picked up and they
both work but they are both pretty dim. (one is reasonably bright after a
30 - 40 minute warm up). Now in the video game market there are kits to
rejuvenate a tube but I don't know what the equivalent would be for a
VT320. Tony? Anyone? Is there anything I can do?

Hi,
I've got a photocopy of the technical manual (mechanical breakdowns/etc)
for a Cipher F880/C880 available to anyone who wants it. It's a
professional-quality photocopy that John L. made and the original claimant
didn't want. Anyone with a need can have it...
Cheers,
Aaron

In Fleischmanns, NY 12430. The town is located in the southeastern tier of
New York (Catskill Mountain) about 100 miles due northwest of New York
City and 110 miles due east from Binghamton, NY.
Incidentally, I forgot to mention that then Tandy 6000 HD comes with a
harddrive and a "memory expansion unit" - also a few 8" disks.

John,
Well I know that A: I can;t afford all of it, and B: I don't need more than
one 11/34, etc., hehe. Anyways, I wanted to ask if you have a spare 11/34
front panel you could possibly spare, since mine has none. Also, the 2nd
weekend in March will be Wang day.

All unicies I've worked with in the DEC world were great about non-DEC
disk controllers. Even 2.9BSD for the PDP-11 loves Unibus SMD disk
controllers in the install (xp driver).
> Any suggestions? I've tried DUA0, DRA0, DBA0, and several others...
ISTR that with third-party disk controllers, it was common to cut custom
SA Backup tapes. We always had SI/9900 controllers so I can't comment to
your Emulex boards specifically, but I know we had to patch the DRDRIVER.EXE
to recognize an Eagle as an oversized RM05. The smaller Fuji drive (a 160Mb)
showed up under VMS and UNIX as a pair of RM03s, DRA0 and DRA1. We didn't
have to do anything to the drives for that one - the geometry was emulated
exactly.
Depending on MASSBUS slot number (set by the jumpers on the backplane, but
typically never altered from factory spec), it's possible that your drive
might show up as DRB0 or DRC0, especially if there are multiple MASSBUS
options installed or even a second Unibus (L0010 card).
One of the features of later SA Backups was that it would print out your
available disk and tape configuration as part of the startup process. If
you are loading such a version and the tape drive shows up but not your
Emulex disk, suspect driver issues with the SA Backup tapes, especially if
they are DEC standard. I think that crept in around VMS 5, though. If
you can get a newer Backup, it might help you identify what, if any, drive
letters it shows up as.

I do have these LSI-11/03 machines in 3' tall DEC cabinets with casters and
woodgrain formica tops - they could pass for end tables. I got them from OSU
at the surplus yard about 8 years ago - 11/03 w/DLV11J, RXV11, RX01 and a
small amount of MOS memory (8K?) They make up an important segment of my
basement work area as portable Qbus space with useful work surface on top.

The 750 kit had one tu58 with standalone backup on it. You need to get
tape or other removeable media that is bootable.

Shouldn't be that bad for the vax alone, the disks I don't know.
