Hello, all:
I got my hands on an unpopulated S100 motherboard by Vector
Electronics and I want to put it together for testing purposes. It's an
active-terminated board and I'm having trouble finding equivalent parts for
two transistors:
NPN power: GE D44C1 or NSI D44C4 (TO-220)
PNP power: GE D41D1 or NSI D45C4 (TO-202)(NSI is National
Semiconductor)
Any help would be appreciated.

Today at auction I purchased from another bidder the following:
A black metal HHC MINI I/O (RL-6002) unit (first I have seen) with Hand Held
computer (RL-H1800) and HHC Color Plotter (RL-P1002) mounted to it.
Panasonic ac adapter RD-9498 first one I have seen.
A Brown leather case for the HHC also my first.
A HHC Printer/Cassette adapter P1004.
Instruction booklet for the HHC models RL-H1000, RL-H1400, and RL-H1800.
A box with 5 Thermal paper rolls for the printer - New.
Several tubes full of plotter pens from Tandy for the plotter.
I purchased four pallets of computers and related stuff for $2.50 plus 10%.
I have not completed listing all the stuff but will update ;list after I get
it done.
The 11/44 I rescued is actually two complete systems in one rack. Last
night I got around to turning up the other system, and was greeted by the
snapping of circuit breakers and the blowing of fuses.. aaahhrg!
Anyway, the H7140 power supply wanted some TLC which it got, but when
recieved, the 'B' system was minus it's Data Paths card, and there were
two spares among all the doc and other stuff, one labled "bad board".
Neither of the two spares work in the 'good' system, and the one from the
good system allows the monitor to sign on, but giving a ??CP HUNG result.
so I have some bus grant/NPG jumer work to do - not a problem.
What IS a problem is that I need one (or two) fuctioning M7904 cards to
make it work, as a printset for the individual CPU cards seems not be
included in the stack I got.
I am also in the market for two or three DD11-CK Single Backplane assy's.
Then, another couple of RL02 drives would round out things. I have found
a nice 9trk subsystem.
I know it's useless to ask about a Unibus SCSI card, so it's possible
that I'll end up buying one... yuk.
Hmmm... come to think of it, an RX02 might be fun, in case of software
finds on Floppies.
I will be brining the working system to VCF 5, as well as (possibly) a
PR1ME 750. I will be in wheel/deal mode then... I'd like to hear back
>from folks who might have some of the above wanted hardware, who will be
at VCF - we can make a deal and do gthe exchange at Moffet Field.
All for now...
Cheers
John

In case anyone is wondering: ftp://zane.brouhaha.com/pub/ModuleList.txt
The list is for non-Q-Bus and non-Unibus cards, and it started out as a list
combining all of the PDP-8 card lists that are out there (each of which had
at least some different data).

Many thanks! I just updated it.

Zane (and anyone else who is keeps DEC module lists),
I was looking up the functionality of a board set I got off eBay
recently (three auctions for the three boards from an H220 "MM8-E")
and notice that for the H212/MM8-EJ, you list G??? as the core
stack. Having just looked it up in the maintenance prints
(B-DD-MM8EJ-B), it's the G646, which you have listed, but not listed
as part of the MM8-EJ.
I can confirm that the G646 _is_ part of the H212/MM8-EJ. You may
"connect the dots" in the Module List.

(now all I need is a working circuit breaker and I can test my "new" H220!)

Ok, it's a small one, but it's wonderful to me :)
I just got a case of 1/2 mag tape EOT markers :) Anyone need a pack?

It takes a serial cable (mini-din 8 to DE-9 or whatever you have on your
PC side), and the PC Connection Kit software, which I believe is now free

Of course, why would anyone buy the POS anyway? It must truly be great to be
able to be a criminal and then profit from it! Umm, god bless america or
something... *sigh*

I for one, have told my parents that should I die, I'd like my computer
stuff to be donated to the Computer Museum, and whatever they don't want,
should be given to RCS/RI and RICM..
