I do have a 12966A BACI interface in my 2117F, but unfortunately no
interface cable for it (or for any of the other interface cards in the
system). Anyone have a spare cable for some sort of reasonable deal?

The HP1000 264x boot rom uses a common BACI board. I have the source code
listing for that
boot rom.
The protocol is very simple, the HP sends "<escape> e" I beleive, and then
listens to a stream of bytes to be sent in the HP standard BBL format.
This is the same format used for HP paper tapes, so all the software on the
HP2100 archive site can be loaded this way. There is no additional
handshaking for each byte as it is read.
(its also the format used to distribute HP-IPL/OS)
This is a quick and easy way to get your 2117F booting.

New subject: MicroVAX 3100 MUX cable?
I've got an early MicroVAX 3100; one of the ones that just reads
"MicroVAX 3100" across the front. On the back of the system there are
three MMJ serial ports identified as 1-3, there's an DB-25M port which
I'd imagine is serial port 0 (the console), and beneath that is a
36-pin Centronics style connector labelled 4-11 with the DEC serial
port pictograph beneath it. I'd gather this is for some sort of serial
port cable "octopus."
Does anyone have a spare one of these cables or a part number for
this cable? Thanks.

New subject: MicroVAX 3100 MUX cable?
With my CXY08-M [M3119-YA] (in a VAX4000/500) I luckily recieved the cables
that went with it. They are BC19N-12s ("centronics-style" 50-pin male to 4
DB-25 male). I could buzz them out for a pinout if you'd like, but these are
apparently the wrong cables for yours as each has only 4 ports instead of 8.
I suspect the difference (being lazy -- not looking up specs) is that the
CXY08 has modem control.

Modem control is the difference, plus the CXY is
probably equipped with higher-performance UARTs. The
extra serial ports out of the old MV3100 Model 20's
extra serial port card were data leads only, DEC423
(compatible with RS232 of course). The 36 pin
'centronics style' cable goes to a H3104 8 MMJ port
'harmonica' breakout.
I used to know what the cable number was; I have the
H3104 in my cabinet of goodies but no cable is hiding
in the drawer with it. Can't recall if I have one or
not; but I think finding the number on the net would
be relatively easy.
Or send a message to Newman Computer Group, Gemini
Digital, etc and find out how much they'd charge for
one.
Oh, and Brian, the serial ports on the back are
actually NOT numbered the way you're thinking; the
DB25 is TTA2:, the first MMJ port to the left looking
at the back of the machine is OPA0: (console), the
next is TTA1:, and the last is TTA3:.
I took a good marker to my MV3100 Model 20e and marked
those on the back 'cause I always forget.

Based on feedback from several sources, the cable I'm looking for is
the BC16C (i.e. BC16C-10 for the 10ft long one.) I managed to find the
following pin out information for the BC16C:
-> The BC16C and BC16D cables are used in conjunction with the H3104
-> Cable Concentrator (Harmonica).
->
-> Specification:
->
-> PVC shielded, 1.5cm diameter.

-> Number Of Conductors 36, consisting of 18 twisted pairs.
->
-> Connectors BC16C - one right-angle 36-way centronics style
-> connector, and one straight 36-way centronics connector.
->
-> BC16D - two right-angle 36-way centronics style connectors.
->
-> Wiring Pin to pin.
->
-> Pin Signal Pin Signal

-> 2 Line 0 Rx+ 20 Line 0 Rx-
-> 3 Line 1 Tx+ 21 Line 1 Tx-
-> 4 Line 1 Rx+ 22 Line 1 Rx-
-> etc etc
-> 15 Line 7 Tx+ 33 Line 7 Tx-
-> 16 Line 7 Rx+ 34 Line 7 Rx-

If I were feeling bored, it would be rather easy to hack together
one of my own cables.

I'll definitely keep this in mind. I would note that the relative
positions of the ports on the back of my MV3100 are somewhat different
from a standard MV3100. Also, I believe the other
fellow's images I'm
referencing here are mislabelled. I think his system is
a MicroVAX
3100/10 and that he's confused the "M30" designation with that of the
vanilla VAXstation 3100 (a.k.a. the VAXstation 3100/M30).

It's obvious some of the ports were shuffled when they redesigned the
case.

That cables should be fairly easy to find. I don't have an extra
on-hand, as I've modified mine by replacing
the HP264z terminal connector (a sort of edge-card connector) with a
DB-9 so it can plug into a PC serial port or an actual terminal (I'm
using DEC VT320's on my HP's, there ought to be a law, but there ain't!).
I do have schematics for the cable, so its not too hard to build one
from parts if needed.
