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.
