Because I had an excess amount of them I used Fujitsu 2333 8" hard drives in
place of the building blocks when building board and block shelves. While
they are heavier than concrete blocks they will not break. I have had
concrete blocks collapse in the past.

Well the RS11 with no suffix is just the controller but since yours has a
motor and a "W" serial number it sounds like one of the fixed head disks
for the RF11. I'm guessing that the tube would connect to the air
filtration system. I've not had much luck locating a picture for
comparison. I'll bet you any amount of money if you were to open it you
would find a single platter attached to that motor inside the housing and a
pair of read/write heads.

I can not see how a suffix is missing, since the label is without
marks other than those used to emboss the "RS11" identification.
As for this being a hard disk assembly, please tell me more.
One other item of identification is that the gold top cover has a
pipe sticking out of it, which is curved and of diameter about 1.5",
and to tell you the truth, I thought this paperweight was some kind
of blower or air conditioning unit. Still, the weight of the unit lends
credence to the notion of it being some kind of DASD (to use IBM
parlance).

This is where the Option/Module guide comes in handy.
RS11 - probably a suffix missing (either B,C, or D and an optional A)
This is a HDA (hard disk assembly) for an RF11 drive which could have two such
drives installed.
A complete RF11 consists of
RF11 + RSO8-M + RS09-M (yours is the RS09-M)

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
work fine without it but I happen to have one that is a bit more stubborn.
Though the NS* 64k dram installed works fine without termination on the bus
most everything else wants it. Odd as I have another that never had
termination!

What software do I need?

Pot and cpu for the H osc, thouse could like it. The cap was garbage.
Still have mine and it still works.
