They're real-time control systems, based around the 21MX processor
family (which succeeded the 2100 (ca. 1972) and 211[456] (ca. 1967))
and running one of several flavors of HP's RTE operating system.
I've never actually used them.
I worked on them for years.... You will still find them in Nuclear Power Plant control rooms,
all phases of automotive testing and even handling online ATM transactions. The E series was
even
used as a fast front end for Burroughs mainframes. Also lots of military applications.
The front panel/door drops down to show the memory backplane. The top three boards are the
two channel DMA, Memory Protect and MEM (Memory Expansion Controller). This was needed if you
wanted to use more than 32K of memory. The back backplane was for the I/O cards. Near the bottom
is the TBG (Time Base Generator). The Model 2117F had more slots and the hardware floating
point processor was a separate box. The more rare version had the Floating Point boards built
into
the top of the regular case. This meant a loss of memory and I/O slots....
These systems had all kinds of I/O available from paper tape puches/readers to mag tapes
to all kinds of hard disk drives, floppies, terminals, A/D, other instrumentation, etc.
Later they had SCSI and various proprietary and standard networking.
Lots of great memories :-)

Ultimately, the definition is up to Bill Whitson. If people start talking
about stuff he's not interested in, or that he doesn't feel to be the
provenance of this list, he'll a) warn people, b) unsubscribe people, or c)
shut the list down. So personally, because I certainly don't want b) or c)
to happen, and I'd rather a) didn't have to, I'll stick to the topics Bill
had in mind when creating this list. If I'm really desperate to talk about
which 486 motherboards are collectible, I'll start my own collect486 list.

I think it was set so as to avoid current/mainstream computer support
questions. (Which I'm sure most of the people on this list could answer,
but that's not why they've subscribed to this list.) The (admittedly
debateable) position that generic PC's are *not*
significant/collectible/etc. and thusly are not the provenance of this list
is a (IMO) welcome side effect.
(Note: some pc's *are* significant or collectible -- lots of portables, the
corner case one (packard bell?), monorails, Kip's Rose Hill PC (to Kip),
etc. -- they're just not the focus of this list.)

Some people (esp. on this list) may not realize it, but there are actually
hordes of people out there who go their entire lives without ever owning a
single screwdriver. Which is why I've got two in/on my laptop case, several
in my laptop "kit", and a swiss army knife with a flat sd, phillips sd,
pliers, and (8^) corkscrew.

It's not so much for *fixing* as it is for *upgrading*. If you want to swap
in a new floppy drive or add memory or what-have-you, it's much easier on
some computers than others.
S-100's were great in some respects -- just lift the ears and the boards pop
right out. Or, drop 'em in the channels and they slide right in. The Mac
8500AV, on the other hand, requires nearly a complete disassembly just to
add some memory.

Well, not quite. You'll have a motherboard problem with Packard Bell, Compaq
and the like -- but many use "generic" motherboards; thus a Baby AT case
would fit anything from a 286 to a Pentium whatever (btw, shouldn't a P5 be
called a Pentium Pro Lite?)
Floppy disks, of course, have been standardized since the original PC, both
in interface and form factor; EIDE/SCSI for hard disks, IDE for CD-ROM's.
I upgrade PC's much of the time (probably sell 10 used systems/upgrades to 1
new system) and can tell you that upgrading _is_ viable in the PC world.
As I recall, there's a little app around someplace that allows you to put
whatever you want on the Wyse front panel display.

I own two complete IBM 5100 systems.
My original machine was fully loaded with 64k and both APL and BASIC in
ROM. It also had the serial I/O card and I used to remotely access the
machine with an ASR33 teletype at 110(?) baud. With the proprietary
vertical market software plus the IBM software, I paid about $64,000 in
1975(?), or about a buck a byte.
The other, purchased ten years later for spares, has BASIC only and I
forget the amount of memory.
I also have the entire library of IBM software released for these
machines and all documentation including the service manuals.
I have two external tape drives and two printers as well and boxes and
boxes of tapes.
I wrote a fully-funcional word-processor in APL for use with the "Paper
Tiger"-series printers. I wrote over 100 user manuals on this machine
and output camera-ready copy.
If anyone out there needs any info or assistance with the 5100, perhaps
I can help.

Where in the world did that come from? Since anything greater than 10 years
old would have been made in 1987 or before there is a whole class of PCs,
XTs, and even ATs that fit. However, 386s(barely), 486s and P5s do not.
Also I think the idea of the list was to not help me be a general "help me
fix my PC forum". it's a common problem that new PC oowners are everywhere
in every forums asking for help usually far from the topic and intent of the
list (comp.os.cpm come to mind). I don't mean help with a older XT or
PC but the "I just got a p6/233 and it doesn't...." stuff.
10 years, that's simple enough for most of us.

I can't solve your geography problem. Here in the USA Alphas are plentyful
as in western europe. The news groups have several a week for sale.
Yes there is DEC software for x86 emulation.
All you need to do is spend money as most all of it is current enough to
buy. It is far to new to even discuss it further here Alpha is a 90s
machine! By definition not eligible for status here till 2000+.

Surface mount offers compact and also better signal integrity for ultrafast
logic. There are many good reasons for surface mount that are in the realm
of quality improvement. Yes, it's take more skill to fix and some of the
parts are not easy to come by.
FYI in the industry there a few descriptions of part of the problem.
Good, fast, cheap, pick two.
Cost of repair exceeds value of unit. Fix/trash decision.
Many machine were made the way they were because technology of the time
balanced against cost were deciding factors.
Allison
There is a local (Silicon Valley) guy who has a model 6122 disk subsystem
with two packs. It has a capacity of 277MB and requires 3 phase power.
Included are also some shipping cases for the packs.
I believe that the subsystem weighs about 200-300 pounds. The dimensions
are approximately 20" x 48" x 30". It was used with a Data General
Eclipse S/140.
My understanding is that the unit can be had for the price of shipping
or for free you are willing to pick it up. I am willing to take care of
the labor for packing and shipping.
This unit will be scrapped soon if a home cannot be found for it.

That is actually a very good idea. I shall dig out some tyvek samples and
cut some inch-wide strips for initial tests. If this is OK, I shall
contact the manufacturers. I'll post results here, but can't make any
promises as to timescale.
FWIW I kept some tyvek samples (from an office supplies catalogue) for use
as gasket paper on my car. Works a treat on things like carburettors, gear
levers, etc. Don't fancy trying it on cylinder heads, though...
Philip.
I need some 5 1/4" 10-sector floppies for my various "classic/antique"
machines. I thought that was what I was buying in a recent on-line
auction. What I ended up with was 16-sector floppies. I don't even
know what uses these; certainly nothing I have. Accordingly, I'm
offering to trade for 10-sector versions. These are Inmac DS,DD, 16
hard sector 5 1/4" disks with envelopes. Quantity 30 (3 boxes of 10).
Two boxes are still factory shrink-wrapped. The 3rd was until I
opened it to verify that I'd gotten the wrong thing; none were used.
Make a trade offer, or alternatively, does anyone know where and how
much I might be able to just *buy* some 10-sectors?

I think we are forgetting one thing. Sure the 7300 would technically be
"worth" more still in the box, but there is a limit to what you'll be able
to actually get. You see these things very often for free (3B2's as well)
on the comp.sys.att newsgroup so what does that make it worth then?
I would have to vote for "just use it."
Any parts can be scavenged from PC's or usually for free on the ng.

I know a guy who has a collection of CA lottery tickets (the $1 scratch-off
tickets) that is complete (except one that he missed). One of each type,
unscratched. Sure, he could be missing out on $10k or something, but to
him, having the collection is worth more. (He also has a collection of
scratched ones.)

Sirs,
I received your name from Bill Yakowenko.
I have a TRS-8080 Color Computer 2 with mod kit to solve the overheating
problem and memory upgrade. My system also includes a disk drive,
multi-pak interface, cassette recorder, x-pad graphics tablet, deluxe
joysticks, external serial/parallel port interface, X-10 light/appliance
controller, light pen, editor/assembler module and parts for an
experimenter's I/O port. I also have OS-9 and numerous other programs and
very much documentation including all original manuals. Finally, I have
many Color Computer magazines, including almost every issue of Color
Computer News.
I'm interested in finding this equipment a good home at extremely low or no
price other than postage.
I'm not sure what services you provide but if you post messages such as the
above would you please post this? Too, what is your website address?
Thanks,
David Fitts

It sounds like your machine needs a good cleaning, the disk drive is not
reading the disk"maybe". I have four working commodore c64 computers,
and the drives need to be cleaned. Even more after laying around for a
long period of time. If your drive turns when you try to load something
it sounds like it could be a dirty drive.
It's not much to go on, but I have seen these small things stop folks in
their tracks. good luck, bad eye bill.
