checking for something to drink while compiling... err: no fridge found!

It's from the TiEmu 2.08 source package.)

I have for free:
2 - apple IIgs's (Both units power up)(please don't ask what
Revision) nothings included - Computers only
1 - SGI Origin I/O module (working system pull)
Just pay shipping or pickup from 48047. IIgs weigh 14 lbs each (with
packing)( or 28lbs together).
Will ship the IIgs's via UPS and I/O module via USPS.
Figure $8.50 Priority for the I/O module.
First come first serve.
Rob
ps. Please USA only
One more to go, too heavy to ship, CT area as well (willing to drive if
someone wants it), HP G30 server, PARISC. No Hard drive/OS.
Hate to, but probably someone takes it or it'll hit a dumpster. Would
rather find it a "good home" if someone is interested tho.

I have a bag of them I salvaged from old 386 and 486s and most are
either low power or CMOS. I've bumped into a few of the older NMOS
parts that are not low power but they do gow down in power when
deselected. Nothing like the old 2114 or 2147 or 2167.
However power it not a prime consideration as the lamps on the FP
are a big load compared to most everthing else.
For me it's board space, heat and a one card solution.

I contacted you a while back, and am still VERY interested in the hardware
information that you were able to figure out on the DN systems. There is
very little documentation on the hardware around.

I'd build one, especially if it was Negibus-compatible. I could
attach a real DF-32 to it. ;-)
Has anyone estimated the physical size? A real PDP-8/S has about 1000
transistors and a lot more passives than that, not counting external
things like a TTY interface (besides serializing the ALU, that's one
of the ways they shoehorned Straight-8 technology into such a tiny
box).
One could always start small and build something simpler from the same
technology - a simple clock or something - sort of a test-drive to see
what the scope of a full processor would entail.

You folks who buy those lots from DoveBid may want to check into some of
the stuff and see if you can locate a tape or two for NASA:
http://news.yahoo.com/s/nm/20060814/ts_nm/space_tapes_dc_2
(Just kidding--NASA would NEVER surplus this stuff, would they?)
Just figured I'd post this out here... I have a collection of old Apollo
DN systems (3000,3010,3500,4000,4500,5500 I think sums it up) I did a
little work on porting NetBSD to and then have just never had the time
to pursue. Might be willing to part with them to someone in the New
England area, since I have monitors with some of them, and OS tapes,
spare hard drives, etc.
Anyone interested, feel free to contact me... really not up for shipping
monitors around, but for someone fairly local with interest I might be
willing to do a road trip.

I have a couple of boards here, not sure what the heck they are...
They're both full-length ISA cards, a 50-pin (!) D-type connector on the
metal bracket, 3 or 4 sets of DIP switches, and a LOT of jumpers. (70-80!)
Both are marked "Frontier TEchnologies Corp. AdCom 2-M Controller", one is
also marked "Version 3" (this one also has a holder for a coin cell on it)
and the other one "Version 5". There's also a Z80-SIO and an 8253 on each
board, and the Version 3 one has an 8255 as well.
While I'm at it, I also have a keyboard here marked "Wyse Technology 1983"
with a really odd 10-pin plug on the end of the cable. Nice individual
keyswitches if anybody wants that for salvage, or can use the cable. This
one' s a little different than a lot of that other stuff in that there's no
LSI on the board. Complete except for the plastic covers not being there.
Anybody have any use for this or parts of it?

Does anyone have any idea on how to remove oil from Microfiche? The
History Resource Center has a stack of fiche with oil all over it
that needs to be cleaned up.
