This isn't exactly what you're discussing, but . . . I've got, in my hand an
S-100 board, not fully populated, silkscreened
"North Star Computers, Inc.
Z-80A Processor Board Z80-A2"
I'll send this jewel via USPS Priority mail, as is, to the first person
whose $3.20 I get in the mail to cover mailing.

Wouldn't you know it, I've got a non-functional pair of Expandorams as well. the first is an Expandoram, the second is an Expandoram II. Both were fully functional when I packed them in their wrappings some fifteen years ago, and boxed them but I think the switches may have gotten fiddled-with in the course of cleaning them. The memory IC's check out. Does anyone have doc's on the required settings?
thanx

I mostly collect DEC hardware -- easy since I worked at DEC for 20
years and was able to partake of DEC salvage when it was open. In
recent months I've started collecting in different directions, mostly
just things which strike my fancy. I can't say that I am trying to
collect any specific type of machines (other than the DEC ones), just
random examples of computers.
As for how much room it takes up... let me put it this way, my S.O.
and I live in one condo, my computers live in another (and I visit to
feed and water and work on them). The largest of the machines are the
pdp-11/10, pdp-11/34a and the pdp-8s. They may only take up 24sqft
of floor space, but they are 6' high, so they take up a fair amount
of volume.
I must say, however, that most of the stuff which takes up room are
all the boxes of manuals, handbooks, disks, spare boards, cables,
etc. that I have to keep them working.
So, I would say in my collection, about 30% to 40% of the space is
taken up by the actual machine collection, the rest is taken up by
the support stuff.

Does anyone here have experience with AT&T 3B2 300 hardware/software?
I apparently have a pile of doc and software which is in complete disarray.
The software is all on 5.25" DSDD diskettes, and i'm not even sure if
i have what i need to format and reinstall an operating system. Does
anyone know what type of hard drives these computers support, or know
if the floppy drive can be upgraded to high density?
I have two base systems, one has either been cannibalized, or merely
every screw has been removed, since everything from the power supply
to the floppy drive is floating free in the case ;) The other unit appears
to be in much better shape.
The student chapter of ACM at the university here had these, so you can
imagine what sacrelige may have been comitted...

Hello,
recently I acquired a pdp11/70 in semi-working condition, but alas,
documentation for the console board was not included :/
Anybody here who is in the lucky position to make me some scans/copies, or
maybe someone knows where I can find 'em in digital (scanned) form ?
Thanks in advance,
Erikb.
Peroidically I do this in hopes of...
I have an IMSAI IMP48 SBC. It was given to me 20 years ago but not the
docs. I'd be interested in finding docs for it even if only a copy.

I collect SBCs, S100 and small dec systems (Robin, Pro, DECmate, pdp-8,
PDP-11, VAX) and the occasional odd (unusual) PC.
How much space, 150sqft room is cubed out. Also three steel racks plus
floor space(roughly 500cuft) in the garage. By actual count some 50
(may have missed a few) systems total. All but a small few are operable
or in use.
The key is that I collect a mix and if they have anyhting in common they
were the systems I drooled over when to were far to expensive to have bought
them all new.
