I have a paperweight of rough dimension 20" by 20" by 6", having a base with a
flange to secure the paperweight to some other device, a motor about 6" in
diameter protruding from the outside of the base, the base being about 2" thick,
with a top cover about 5" thick. The base is grey metal, perhaps aluminum,
while the top cover is gold in color. Now, this item has a layer of what appears to
be a foam material which provides a seal between the base and top cover, and
out of one side come five cables, four with ribbon cable and end connectors
marked W033, and the fifth with a round cable and an unmarked connector.
This device is a DEC product, having the appropriate lable, with the following
information:
RS11
WF6581
Please, can any of your tell me what this item is, and how it may be used. I
can tell you that it weighs between 70 and 100 lbs, as judged by my own
strength.

well, you should be running warp connect, which includes os2 peer on the
mod80. if you dont have warp connect, something tells me there was tcp/ip for
os2 version 2.1 that you could possibly get, but i'd need to research that.
best thing is to post the question into one of the os2 groups on usenet. many
people would be glad to offer help.
I have my (fairly small - mostly standard desktops) collection housed in my
basement. I have a fairly large drafting table (workbench), with cement
blocks near the back (on top). I have 3/4" plywood shelves, 3 levels high.
The first and second shelves are computers, and all the monitors are on top.
They've been like that for tow or three years, now, with no problems.
The only downside is that the cement blocks get to be pretty heavy. They're
not bad for a garage, though, if you don't plan to be moving them. They're
easy to find at demolition sites, too. I got mine for $1 a block.

Standard NS* horizon does not have any termination passive or active. Most

most everything else wants it. Odd as I have another that never had

Thanks for the offer Sellam! It's been *years* since I learned French and

Make sure you keep tabs on the costs. Good luck in finding it.

Hi Sellam, I've got an Operating Manual, however, it's in French. Probably

Actually, I'd like to swap it for an English one if any of the
French-speaking folks in the world have an English TEK 31 manual.

Seriously, the VFC Vintage criteria if applied as it is to old cars a
chopped and decked 49 Chevy is a valid entrant even if the engine is
a later model. The key is it's not catagorized as stock/restored.
Like Tim said, nont one member of LICA has a "pure" machine. Some part
was non stock and often the reason was price or availability. I can't say
how many Altair and IMSAIs with floppies from neither vendor were seen.
If anything a pure machine was more the TRS80 era or later when a vendor
would actually sell all the desired parts.

Yes William. I knew there were a few folks on the list who delighted in
letting a spammer know they were not welcome here by tracing their often

Sellam,
I've got a manual which could be scanned - It has one of those plastic
comb bindings (Acco?) which needs replacing anyway. I think it is
original since the cover is the typical Tektronix type with the cutout
window that shows the title page. I can make a copy, or possibly loan it
to someone local (Sacramento|Bay Area) for scanning.
I was planning to bring the calculator and manuals (operating+statistics)
to VCF to look for an interesting trade.

The s/w should consist of an interrupt driven device driver for the NIC,
with any interrupts providing for input servicing. Now, this device
driver should also provide the transfer of processor control to the IP
layer. So, my suggestion is that you start with the NIC software. Under
DOS you should also be able to implement the IP stack by extraction

Interesting set of rules, with an interesting sense of "purity". In
the real world, of course, someone who bought an IMSAI and populated
it with only IMSAI peripherals was a fool. And it also leaves out
the richness of computing that is (was) possible - take a look in the
back of a late 70's BYTE and you'll see hundreds of manufacturers making
a huge variety of S-100 boards. Yet any computers demonstrating
this richness, so important in the early personal computing industry before
the dominance of the PC-clone and the subsequent dull monotony of
compatibles, lose points in this proposed judging scheme. Oh well,
different strokes for different folks.

Seems to me like last time I took one of the classes leading to "ESD
Certification" the standard resistance for "primary packaging," which is
what encloses and otherwise directly contacts the packaged items, was 1
MegOhm per inch. That is high enough resistance that you can't hurt
yourself with inadvertent contact with the AC mains, yet low enough to
dissipate static from the usual sources with little risk to the components.
