So I would have thought. Apparently you can post after attempting to
join the list, but until approved by Jay, you don't receive any
messages from it. I'm reading this from the list archive.
:(
I have inventoried my collection of STD Bus boards, docs and enclosures.
There's a lot of stuff there, complete with documentation for almost 99%
of it. About 1/3 of the boards are still sealed in the original bags.
I really, really want to move this as an entire lot. If anyone is
interested, please e-mail privately and I'll send you a list.

[I originally sent this on the 23rd but it seems to have disappeared into

show up later.]
I'm looking for 7 or so junk computer cases in or around the Houston area.
A little over 10 years ago I installed a number of high end (for the time)
machines for a local company. I went back in 2001 or 2002 and decommissioned
them after Tropical Storm Allison when the projects they were hosting were shut
down. The machines been sitting in a corner of the equipment room ever since.
I've been told I can now remove them if I want them, but there is a catch.
Asset management wants "something" to show them as removed from inventory. They
don't much care what they get because anything over 3-5 years old (according to
inventory sheets) gets sent to the metal scrapper.
So...I'm looking for 7 or so junk computer cases. The systems I had in place
there were large full-sized deskside chassis, but something like mini-tower PC
cases should do. It would be best if they were completely empty no-name junk
cases as I really don't like sending anything to the metal scrappers (I still
use a number of well made heavy duty AT cases for my personal machines).
I kinda wish I hadn't gotten rid of all my own junk PC cases 5-7 years ago but
I'm sure there has to be someone in or around the Houston area with some junker
cases still sitting around.
I could probably also use some anti-static bags too as I have a bunch of spare
parts in a cabinet there that are sitting in bins. I can't take the bins but
the spare boards and drives will go with the old systems.
Replies should probably be off-list. Even though the machines I'm attempting to
save from the scrapper would be on-topic by now, they aren't DEC, Sun, etc and
would probably be boring to many list members. Also, please maintain a subject
line I can easily spot as I'm often flooded with spam.

Steve,
The only problem that I've had with 1050's is that the felt pressure pad
that replaces the top head will fall off. I don't remember the exact
symptoms because it's been a few years. Take a look, it couldn't hurt.

I am in need of this thermal Paper,I woek for Labarge Inc. and have an
HP 85 used for a tests system. If you still have the paper E-Mail me at

Corvus made a family of external hard drives using a common bus interface
(quasi-network, actually). There was an interface board produced for the
DEC VT-180 that, along with the driver software, permitted it to use files
on attached drives.
I have never seen one, but presume it's a small internal add-on (possibly
piggy-back style) circuit board or a little external box. It would be
labeled 'Corvus' or 'Corvus Systems, Inc.'

----------Reply:
I have an external Corvus drive enclosure (the small MFM version, not the
8" IMI 7700) that I used to house an external HD for another system, but
I still have the original interface board if anyone's interested. I think it was
an Omninet drive; the only connection to the outside world AFAIR is a
3-pin header plug.

Venner Electronics made lab equipment in the 60's and maybe early 70's.
What I've seen are digital voltmeters, frequency and period counters, etc.
The decade counter modules you have seem most applicable to frequency
counter and timing applications but I think they were used as part of the
A/D scheme for some of the digital voltmeters too.
HP, Berkley Nucleonics, Ortec, and other companies used in their equipment,
and sold to other companies as well, decade counter modules etc.
>from the 50's onward. I presume "Transistor Decade Unit" was to
differentiate it from the "Tube Decade Unit"s that I am very familiar with.
If sold to the nuclear instrumentation industry they are usually called
"scalers" instead of "counters".
Some have direct readout of 0-9 lamps on the side, some have nixie
sockets, others simply divide by ten and provide outputs but don't
have displays in themselves.
Tim.
Do you still have that Motorola M68HC705KICS K-Series ICS/Programmer?
