I just got back from a three day hamfest. Boy, did I get a LOAD of
stuff!!!! My truck was dragging all the way home! It'll be days unloading
and sorting this stuff.
One of the interesting things that I got I **think** may be part of an A
series HP 1000 but I can't find any of the part numbers in my HP catalogs.
The serial number on the power supply indicates that it was made in 1980.
Here's a description of it.
A large 19” rack mount box, marked “Hewlett Packard 12979B I/O EXTENDER”
It’s 19” rack mount box, 23” deep and 9” tall. It has a flat front cover
held on by two 1/4 turn fasteners. It has nine slots in the back and nine
slots in the front. The back slots are numbered 0 through 7 then 10. the
front slots are numbered 11 through 17 then 20 and then DC PC. These cards
are currently in it.
slot PN Marking
(3) PN 02100-60060 marked TERM
(11) and (12) PN 12979-60029 marked I/O BUFFER
(13) PN 12566-60032 marked MICROCIRCUIT
(14) and (15) PN 59310-60101 marked BUS I/O
(16), (17) and (20) PN 12566-80024 marked GRD TRUE IN OUT
(DC PC) PN 12898-60001 marked EXT. D.C.P.C.
All the cards have a card edge connector on the outside edge except for the
TERM and EXT DC PC cards. I also got a LARGE box of cables that I *think*
are for this device. They all have connectors that plug onto the card edges.

Tony, you've only heard part of it. Here's a BRIEF list. There's no
telling what I've forgotten and left out!
A large portion of a HP 1000, a like new HP 92 with case and manuals,
three like new HP 97s with cases and manuals, a mint 11C with manual and
case, PILES of HP 9000 200 and 300 series computers, hard drives, cards,
etc and a huge external HP SCSI drive. I also hit the motherload of HP
cables. I got boxs full of them. I also found two COMPLETE HP 64110 Logic
Developement Systems (CPUs, hard drive with software, cables, ICEs, etc), a
HP 3465 DVM, a real time clock module for a 9825/35/45, a bar code wand and
box for the HP 150, a HP polar display unit and more, more, more! Probably
one of my best finds was a HP 3468 meter with the HP-IL interface. I've
been trying to find one of them for ten years. Now I just have to find a
place to put it all!
Yeah, but catalogs are faster! Here's what I've found out so far:
A large 19" rack mount box, marked Hewlett Packard 12979B I/O EXTENDER
It’s in the 1981 catalog and is for the HP 1000s. They call it a Dual
Port I/O Extender. It cost $5250 but it doesn’t give any details though.
slot PN Marking
(3) PN 02100-60060 marked TERM
(11) and (12) PN 12979-60029 marked I/O BUFFER
Since these have the same part number as the chassis I think these are
part of it and probably are the interface to the 2100 or 21MX CPU..
(13) PN 12566-60032 marked MICROCIRCUIT
(14) and (15) PN 59310-60101 marked BUS I/O
I found this in the 1977 catalog. It’s called an Interface Bus Controller.
The description says it “allows any 21MX or 2100 Series processor to
interface with instruments that are programmable via the HP Interface Bus. “
(16), (17) and (20) PN 12566-80024 marked GRD TRUE IN OUT
The 1977 catalog shows an item called a Microcircuit Interface, PN 12565.
It says that it provides 16 bit Input and 16 bit Output DTL/TTL compatible
lines. I think the Microcircuit card and these cards form three of these
sets.
(DC PC) PN 12898-60001 marked EXT. D.C.P.C.
No idea yet.

I am guessing here, because I don't have an HP catalogue at all...

Here's a description of it.

Guess : It's an expanison box. Something to stick more I/O cards in when
all the slots in the CPU are full.

Terminator? It would agree with there being no connector onit.
(11) and (12) PN 12979-60029 marked I/O BUFFER

What (large) chips are on the cards? Sometimes that will help you
identify the function.
