Hi,
All of this HP 1000 talk got me going on mine. I have
most of the drives, paper tape punch and tape drives and
a real nice 2117F. But thats where it stops. No Cables
Does anyone have a stash of these. I have no cables and
cant seem to find anyone that does. It seems that most
of these are offered with out the cables. I would guess they
all go to bulhead connectors and are just easier to slip off the
connector on the cards.
Need these at minimum
- Console 12966a
- HPIB disk 12821a
- HPIB Mag tape 13183
Also Trying to figure out 2 cards
HP 12250 60001 and a FDS n612 4256-001

EDAC makes card edge connectors that mate with the usual 48 position
connector cards, but they are not standard stock items that you can
order anywhere that I have found. I requested a sample and got a
couple. I forget the exact part number without checking.
It might be worth finding out what the item cost and minimum order
would be to order some of these, and how long the lead time would be.
There was also someone selling used connectors+hoods with the rest of
the cable chopped off on eBay a while back. Something like a couple
of them for $10. My guess is that he has more of them but just hasn't
listed any in a while.

I erroneously purchased one of these items thinking it was the same
connector as for the card edge on the 2648A, but its not the same.
I am looking for the right connector for the 2648A. I tried looking
in DigiKey and so-on but didn't see anything that looked right.
What's the URL for EDAC?

What was different? Did you run in to the single vs.
dual registration
issue?
Its the wrong number of pins and the wrong physical size (too big for
the 2648A).

Oh good lord, how embarassing. You said 2648A and my brain was locked
thinking paper tape reader. Total brain lock on my part. Sorry.
You're talking about the connector that goes to the back of the terminal's
async card. That is NOT the standard HP I/O connector, like you see in the
rear of an HP cpu. I'll take the standard HP I/O connectors off your hands
that you got from ebay ;)

Oh, and
remember the cable for the 2648A isn't just hardwired at the reader
end... on that end it's a v.35 kind of looking connector only taller (I

Are you looking for the card edge connector for the async card in the

connector?
Does this look right?

Yes, that looks like the right kind of receptable for the card edge.
However, I was looking for something that could be used in a cable;
that picture shows a connector designed for a circuit board. Yes, I
could kludge something together, but I was hoping to find something a
little more designed for a cable connection.

Yes, it would

That was ebayid SammySlave, he's in San Jose CA. I
suspect he has more.
Sometimes the ones he puts up are single registration, some are dual.

This is the connector I got from EDAC, except 305-048-500-202 instead
of the stocked 044:

There are various mounting hole options encoded in the last section of
the part number. See the full spec for details.
http://www.edac.net/downloads/305-315-355%20Series%20Spec%20Sheet.pdf
Digikey quotes 244.06 / 25 = $9.76 for the 305-050-500-202 so that
might be about what the price would be for the 305-048-500-202.
That's about twice of SammySlave's used eBay price (or about the same
after paying him shipping), but no hood.

(on HP) No, I've never run into any cabinet bulkhead
connectors except for
DB25 panels (well, ok, some of the 13037 stuff). Everything else was direct
cable from device to interface. On a properly buttoned up HP it wouldn't be
easier to slip them off the cards, what with ground cables sometimes screwed
in and the PCA retainer bracket locked in and the rear panel over the I/O
cards for proper ventilation and the battery backup over that ;. That's not
to say everyone observed those recomendations of course.
- Console 12966a
I don't have a spare, I
make more anytime I need one from spare connector
hoods. The jumpers in the hood for wiring to a BACI are a pain.

I may have a spare, what

- HPIB Mag tape 13183
Hummm I don't have

New subject: HP 2112A
All the HP 21MX posts got me interested in finding out what I have with the
HP 2112A I recently got and what I'm missing. The back end (where all the
I/O cards go) is empty. In the front there is the DCPC, Memory Protection,
M.E.M. (Memory Extension Module), 3 memory cards and Memory Controller. I
believe I can see 3 loader ROM chips installed on the CPU board (assuming
I'm looking in the right place - front right side of the board as I'm facing
it). Of the 3 optional Control Store modules in the back, the middle one is
mounted under the CPU, but the other two are not there.
The back label says "2112A" and lists the following options:
12978A (Writeable Control Store Diagnostic)
12992B (Disk boot ROM)
12992C (Terminal boot ROM)
I figured out from the bitsavers document and another online document that
these are the 3 ROM options I saw. The paper tape loader ROM is soldered in
with the M-series machines, according to the online documents I read.
12897A (DCPC)
12892A (Mem Protect)
13187Ax2 (16k Mem)
So it looks to me like I need some I/O boards (13175 disk drive interface,
12966 or 12968 terminal interface, 12597 paper tape interface), and probably
the other Control Store modules to flesh this thing out (not to mention the
cables to connect to peripherals). Does all that sound right?

That's the correct location. Optional ROM 1 is the socket nearest the
front of the machine. 2 and 3 follow in order.
Of the 3 optional Control Store modules in the back,

Looking from the back of the machine, the left-hand control store PCB
should always be present; it contains the base set ROMs and is connected
with a ribbon cable to the left-hand CPU board connector. If you have a
MEM card, then there should be a second control store PCB containing the
DMS instructions. The second and third boards plug into the first and
second boards respectively; no ribbon cables are used.
If the middle one is present and the left one is not, then either the base
set board is in the wrong location or it's been removed from the machine.
Part numbers on the board and/or ROMs will tell.

That's correct. It's always loader number 0.
12897A (DCPC)
12892A (Mem Protect)
13187Ax2 (16k Mem)
So it looks to me like I need some I/O boards...
First, you'll need a base set PCB, unless the one in position 2 is
mislocated.
...(13175 disk drive interface, ...
That's a "MAC" disc interface, so you'd also need the 13037 MAC
controller
box and an associated drive (7905/06/20/25). An alternate would be the
13210A disc interface and a 7900/01 drive, or a 12821 HP-IB interface and a
corresponding HP-IB drive.
...12966 or 12968 terminal interface, ...
Note that only the newer HP RTE systems supported the 12966/8 interfaces,
and then only with HP terminals (264x, 262x, etc.). Alternates would be
the 12531 (teleprinter) or 12880 (CRT) interfaces. The latter works with a
broad range of terminals and HP OSes, although with less efficiency (more
CPU load) than the 12966/8.
[...] and probably the other Control Store modules....
The M-Series had a small control store address space compared to the later
E/F-Series, so there were few firmware options. Beyond the base set,
you'll need the DMS instructions PCB to support your MEM card (although DMS
isn't overly relevant with 32K of memory). The 12977 Fast FORTRAN
Processor instructions help to accelerate some commonly-used routines,
although HP operating systems came with software equivalents, so it's not a
necessity. The "B" version of the FFP included the DMS instructions, so
that only one control store board was needed for both. I think DS/1000
(Distributed Systems) was the only other M-Series firmware option available
from HP.

Here's a photo of its ROMs:
The ROM part numbers and the board number (5060-8380) show that the board
is a "Fast FORTRAN Processor II" microcode set. This contains the FFP
instructions plus the dynamic mapping instructions (DMI) that work with
your MEM board in the front card cage.
If that's the only microcode board under your CPU, then you're missing the
base instruction set board, which must be present to use the machine. The
machine should power up, but the front panel won't work, as that's
controlled by microcode on the base set board.
This board appears on page VI E-4 of the HP 1000 Engineering and Reference
Document, available here:
http://www.bitsavers.org/pdf/hp/1000/1000_MEF_EngrRef/
The three ROMs all have 12992 on them, the first in
light pencil (not
visible in the picture below)...
Is it 12992-something? The "something" will indicate what ROM it is.
...the others with a label as shown here:
http://home.comcast.net/~richardlynch3/hp/opt_roms.jpg
From the photo, the installed ROMs are:
- U36 (ROM #0) 1816-0420 is the 12992K paper tape loader
- U16 (ROM #1) is unknown
- U15 (ROM #2) 12992-80009 is the 12992C 264x CRT tape cartridge loader
- U13 (ROM #3) is the same as #2
U16 does not appear to have an HP part number on it, although your first
message said that it was a disc boot loader. The HP part number might be
on the underside; you might wish to remove it from the socket to check. Or
the fact that the "chip label" is in pencil might indicate that it's a copy
of the HP chip that was made by the owner. Or it might be a custom disc
boot loader.
U15 and U13 are designed to boot from the DC-100 minicartridge tapes that
are present in (most) HP 264x-series terminals, e.g., the 2644, 2645, 2647,
or 2648. A 12966A or 12968A interface card must be used with these
terminals when using the 12992C boot loader ROM.
Why are U13 and U15 both labeled "80009"?
Are they the same chip or is
that a date code?
Same chip.
Section 7 of the "HP 1000 MEF CE Handbook" has tables of board/chip part
numbers and associated descriptions that will help to identify these sorts
of things:

I'm not sure if the paper tape loader ROM is
present. U12 is empty - is
this where it was supposed to go:

It's U36, visible in your "opt_roms.jpg" image; see page 13-8 of the CE
Handbook above for a locator diagram.
One more photo of the numbers on the CPU board:

The board number, 5060-8352, indicates that it is an M-series CPU with date
code 1838 (38th week of 1978).

OK, per page 13-31 of the CE Handbook, that would be the 79xx disc loader
ROM. It's possible that the white stick-on HP label fell off at some
point, and the owner wrote the part number on the chip in pencil. If
you're curious, you can check the ROM contents against the loader listing
on page 13-18 of the Handbook (when you get a base set board, that is :-).
Top priority would be to obtain that base set microcode board. You really
can't get anywhere without it.

All the HP 21MX posts got me interested in finding out
what I have with
the
HP 2112A I recently got and what I'm missing.
Woohoo, a M series. Those
aren't so common.
The back end (where all the I/O cards go) is empty.
You'll want some I/O cards. Also get a TBG (time base generator), many OS's
want this.
In the front there is the DCPC, Memory Protection,
M.E.M. (Memory Extension Module), 3 memory cards and Memory Controller.
Sounds like
you're all set there. Make sure you have the DMS daughterboard
in addition to the base set microcode daughterboard. I *THINK* I have a
spare DMS microcode board for the M series.
I
believe I can see 3 loader ROM chips installed on the CPU board (assuming
I'm looking in the right place - front right side of the board as I'm
facing
it).
Do a IBL of each loader rom and jot down the first 8 words or so of the last
64 words of ram. Then you can look in the loader manual and see what loaders
you have. Some versions of the M series metalwork allow you to see the rom
part numbers directly though, that may be more expedient. Don't bother with
the options written in the front door panel, they are often outdated/wrong.
On some boards loader rom 0 is soldered in and is paper tape. However, I
have a few M series boards where ALL the roms are socketed, and I have found
other loader roms besides paper tape in rom 0, so check all 4, not just the
3.
Of the 3 optional Control Store modules in the back,
the middle one is
mounted under the CPU, but the other two are not there.
I do not recall for sure if
the base set microcode MUST be the bottom right
(as viewed from the top front). I think it may actually be able to reside in
any of the three positions, but I could be way wrong about this. The base
set is of course required. Then you'd want the DMS (optionally) microcode
too if you want to use memory above 32kw (and have that much memory). Note
that if you want DMS, you have to set jumpers on boards in addition to
installing the microcode. Ditto if the DMS option was removed.
The back label says "2112A" and lists the
following options:
12978A (Writeable Control Store Diagnostic)
12992B (Disk boot ROM)
12992C (Terminal boot ROM)
I figured out from the bitsavers document and another online document that
these are the 3 ROM options I saw. The paper tape loader ROM is soldered
in
with the M-series machines, according to the online documents I read.
Not on all M
series machines it's not. I have never seen or heard anything
about 12978A Writable Control Store Diagnostic. I'm very intruiged.
12897A (DCPC)
12892A (Mem Protect)
13187Ax2 (16k Mem)
I'm assuming theres MEM (memory expansion module) and a
memory controller
(2102) in there somewhere too?
So it looks to me like I need some I/O boards (13175
disk drive interface,
12966 or 12968 terminal interface, 12597 paper tape interface), and
probably
the other Control Store modules to flesh this thing out (not to mention
the
cables to connect to peripherals). Does all that sound right?
You want some I/O
cards, the problem is which ones. Do you have any
peripherals for it already? I use mostly 12531's, and some 12966's for
consoles. Paper tape can be one of several boards. There's several different
disk drive interfaces too, depending on what drives you have or want to get.
You may or may not need other control store modules, depending on if the
base set must be on the bottom right (ie. is what you have the base set or
some option set).
Sounds like you have a handle on it to me.

Subject: HP 2117f cables needed
Hi,
All of this HP 1000 talk got me going on mine. I have
most of the drives, paper tape punch and tape drives and
a real nice 2117F. But thats where it stops. No Cables
Does anyone have a stash of these. I have no cables and
cant seem to find anyone that does. It seems that most
of these are offered with out the cables. I would guess they
all go to bulhead connectors and are just easier to slip off the
connector on the cards.
Need these at minimum
- Console 12966a
- HPIB disk 12821a
- HPIB Mag tape 13183
Also Trying to figure out 2 cards
HP 12250 60001 and a FDS n612 4256-001
Thanks, Jerry
