A little while back I asked about shelving. Noone suggested anything.
I found what seems to be a good solution at about half the cost of the
next nearest offering, so I thought I'd share.
I had been looking at wire rack shelving. Some nice wire racks on casters
had been purchased at work from Costco, so I started looking at those.
Costco had Safco "LAN Management System" racks 72"Wx29"Dx73"H for $340,
48"Wx29"Dx73"H for $250, 30"Wx29"Dx73"H for $205. (Casters were extra.)
They also had Safco wire shelving: 4-shelf 36"Wx18"Dx72"H for $120.
Online I could find racks for comparable prices or a little better
(like $5) and comparable shelving for $80.
I found nice 5-shelf wire racks at Walmart for $40 ea. 36"Wx16"Dx72"H,
black finish. Each shelf is rated for 200 lbs evenly distributed.
They have levelling screwcaps on the feet. "5 Shelf Multi-Purpose Rack"
by NSF is what the box says. UPC 0 34886 00012
Using this shelving, I can stack 10 terminals vertically, 2 per shelf
for 5 shelves, which is a tremendous space savings.
I had to go to several Walmart locations in order to get enough shelving
units, so I don't know if these are end of inventory "priced to move"
units or not. This shelving is not currently listed on Walmart's web
site, but each store in the Salt Lake City valley had the units. There is
also a 4-shelf unit standing 52" high with 14" deep shelves. Most of
the stores had these, with fewer having the taller 5-shelf variety.
The shelf heights are adjustable in 1" increments and no tools are
required for assembly or disassembly. They seem sturdy enough when
fully loaded, but I wouldn't want to trip and fall into them and put a
big transverse load on the whole system. It would most likely fall
over and have a danger of crushing you with what I've got loaded into
them. I certainly wouldn't want to have 10 13" CRTs dumped on me. I
should probably secure them in case of earthquake...

As I understand it, DEC agreed not to make consumer goods, and VAX
agreed not to make computers. To an adolescent mind back in the mid
'90s it seemed a bit absurd and a waste of time, but maybe not so much
anymore.
Well, we used lots of PDP-10's in the timesharing (oops, marketing calls
it REMOTE COMPUTING)
business in the '70's and '80's. By the late '80's this business was
dying fast. But it was fun.
Yes, Compuserve was a big player. I worked with ADP Network Services
(originally Cypernetics Corporation);
we had quite a few PDP-10's. (about 25). Also, we probably had 100 -
200 PDP8's and PDP-11's
as network nodes. When DEC released its KS10 processor (minicomputer
architecture), we ported
TOPS-10 to run on it. We ran about 75 or 100 of these as dedicated
mini's for individual clients.
As I recall DEC only sold the KS10 with TOPS-20. For better or worse this
machine was superceded by the VAX.
What were these users doing? Mostly interactive management applications
- financial models
(think of Fortran meets Excel); stock analysis; engineering analysis;
statistical analysis & forecasting.
It really was "personal computing".

Brad

Especially interesting given the scorn that the DEC-VAX agreement from
the '70s had.
The "why" question still remains on a technical level, given that all
of their "consumer" products still are data processing equipment,
predominantly based around microprocessors. They may not be intended to
be general purpose computing machines, but then again neither was the
PlayStation 2 et al, and look what's been done with them.
It's not my intention to exacerbate the situation,
being that this lists already has a rather high drama
index, but concerning the previous rant, I don't at
all see the point of such non constructive
criticism. If your "needs" aren't being met, simply
move on. I for one find it to be unique and often
useful
exchange. The old adage sure applies here that if
you can't say anything nice...
And it wasn't that I found the reply funny, but
rather laughable. Nearly comic.
Just my 2 farthings.

I believe that the APC follows the NEC 9801 convention, but I'm not
certain. The BIOS calls are very diffierent from the PC version. A
Google should turn something up; I know the calls are mentioned in
Ralf Brown's interrupt list--and there was a rundown in one of the PC
rags--maybe DOS/Windows Developer? I probably also have a list in my
files.

Sun seems to use some odd plastic compound or alloy with two different
types. I usually use MEK (methyl ethyl ketone) for welding plastics,
and usually it either has no effect or works well, but with the
Sun-type (I've seen it elsewhere, but first on Suns) plastics it
dissolves one component but not the other, and the plastic turns into
this yucky granular stuff with no strength to speak of (the bond will
hold, but only until you move it). The epoxy kind of worked (it was one
of the trim pieces off of a SPARCstation 20 (one of the $1 Boeing
specials- thanks for the heads-up) it holds together O.K., but it's a
little loose now (epoxy is much slower than MEK, and stuff moved).

The faceplates of Overland Data tape drives are like that--try any
"regular" solvent such as xylene or MEK or (worst) acetone and the
plastic just crumbles away. Methylene chloride does seem to work
better--and any gaps can be filled in with auto-body resin filler
(Bondo) and the whole mess painted to match.

Probably a very shrewd move, too. Computers are a commodity item
now; just the thing you don't want if you're trying to run a high-
profit margin operation. Better to produce new widgets that folks
will pay a premium to own.

I probably have at least 1 issue of Byte that
features advertisements for this computer, but a whole
big box became unexpectedly drenched, and I don't have
the heart to look at it. If perchance anyone has a
scan of this ad, and you'll know what I'm talking
about if you've seen it, it would be awful nice to get
a scan of it. I bought one of those kits to make your
own T-shirts a while back (especially since it was
free after the rebate) and I thought a shirt with the
D68K logo would look sick. (Trouble is I have to send
for different transfer material. The stuff that came
in the box is only for light colored shirts, and I
thought black would be a better deal).
