<I'm interested in finding out all about the Intel 4004 which, if history

No problemo... according to my 1979 Intel component databook... the last
year it was in the data books (along with the 4040).
Oh, as a note the 8008 had a shorter life than the 4004!
<Was the 4004 chip itslef a microprocessor?
Well yes, but I'd have to know what you consider a uprocessor. It was
complete in that it contained the Instruction decode, ALU, registers
and all the basic timing and control.
<Did it require support chips to actually make it functional?
Yes, a clock generator, and a pot load of logic or specific support
chips. I've seen 290x based designs that used fewer chips total.
<I recall that the 4004 was a part of a chip set upon which you could
< build applications.
Yes there were but, the 4004 could be used alone...awkwardly.
<Was the 4004 a serial or parallel architecture?
Parallel. Instructions are 8bits and data/arithmetic paths 4bits wide.

I'm sure there are at least a couple of g00r00's on this list who can
provide the information I seek.

While I'm not against it... this is an example. Like what kind of PDP-??
There are PDP-11s, -8s, 10s and others, all different, some quite large.
Even within a family like PDP-11 there are unibus machines (11/20, 11/34,
11/44...), Qbus machines (LSI-11, 11/23, 11/73...), CTbus (pro350, 380),
bounded PDT-11/130, pdt11/150. There is where a little research
beforehand is needed. A pro350 is desktop, an 11/44 could easily be three
racks and a washing machine disk. PDP-8s there are at least three major
buses used and variations in the family ranging from the small decmates to
an older straight-8 or 8I. When put in context "I want a PDP." is a
pretty broad statement and could put you in the position of trying to
handle something larger in scale (or smaller) than desired. I'm not
saying don't but, having a PDP-10 (ka10) means you have at least 40-200
square feet just to set it down and three phase power to run it.

These net auctions cause a great deal of thought in my brain, which
is driven by a pure-gold capitalist heart. At first I thought they'd
be a great place to pick up bargains on trailing-edge contemporary PC
and consumer stuff, but whoa... look at those prices! Sure, they start
at $9.00, but you can watch them zoom right up to conventional Best Buy
or CDW retail prices *or more*. The question "Yeah, but who pays retail?"
is answered "Lots, and many pay more." Someone did their homework when
they developed this online auction concept. Or perhaps it exposed its
true nature once someone implemented it, and let the market drive it.
(Although I wonder if we don't know important details such as the
rate at which the auction house successfully collects its percent, or
whether auctions have been rigged by shills working for the seller, etc.)
So when the historical computer sells for what we (the dumpster-diving
cheapskates) see as inflated prices, we may instead me seeing the evolution
of a "retail" price for our old junk, and perhaps the anecdotal reports can
provide a "dealer" or "wholesale" price, or at least provide the mean.
We grimy collectors know that much computer equipment is tossed in
the trash, fed to scrap collectors, or is still sitting in warehouse corners.
That alone fuels a desire to pick up collectibles for no cost.
Just yesterday I introduced myself to a local junk dealer. I missed
some kind of mainframe from a local business by a month... but now he
knows he can sell me junk for higher than the scrap value, so perhaps
he'll remember me for next time.

Russ,
If you get more than one person interested, I believe I can get a couple copies of Win 3.0 for folks.

I have a new copy of Windows 3.0 for sale. It's never been used but the
shrink is off of the outer box but the manual is still wrapped and the
disks untouched. It comes with 1.2m 5.25" fl;oppies but if someone wants
this and needs a set of 1.44m 3.5" disks I can make those and add them
to it.
I need $15 for it with only the 5.25" disks, mailed to anywhere in the
48 continental states. Add $2.50 (17.50 total) if you wish a set of
1.44m 3.5" disks included (copies from the 1.2's) to cover the floppies
and the little extra weight.
I have only the one copy so first come first served.

Ditto. I'm somewhat surprised that you can't find anything cheap. In
the WantAds, which generally sell Commodore 128s for $300, the
Compaq portables go for $10 a piece.

Yes, that's all a decmate needs, though I haven't seen one with an
8" drive. I have the manuals and 5.25" diskettes of WPS, as well as
a couple of other random DEC 5.25" disks (MS Windows 1.0 for VAXmate
and something else). I ought to download RX8 (or whatever the OS is
called) and try it on my DECMate.

Uh-huh. It's time to move out of my apartment. Is the HP 3000 any
good (in terms of how interesting it is)?
