Pretty sure I have a binary copy of all known 12992's, the ones I use I just
burn out to a set of blanks. The 7974 loader rom uses the boot loader
extension firmware for DS/1000. Are you actually running ds/1000?? I haven't
seen anyone get that up and running.
I'll see if I can dig up the bin (or an already burned chipset).

Hi Grant,
I looked at my collection and I have the 67-69 ROMs, which I also identified
as the DS/1000 ROMs (Distributed Systems Network). I also have a
91740-80033/34/35 set which I don't know what it is. Does anyone know?
Anyhow, looking at the ROMs and dates, I suspect these are E/F microcode
only and would not work on the 21MX. So I think you'll have to go with one
of my cables, a standard mag tape card set and disconnecting your HPIB card
from the 7970 - so you were right from the start.
I would still be intrigued to see if anyone has the 70-72 set, and did not
know they were a DS/1000 extension, thanks Jay.

Those are DS/1000 revision 1826.
Page 3-130 of the HP "Communicator/1000 for Software Update 6.0"
(5951-6201, December 1992) has a full list of the DS/1000 ROMs and
revisions, as follows:
91740-80001/02/03/16 -- Rev. 1740
91740-80018/19/20/17 -- Rev. 1813
91740-80033/34/35/48 -- Rev. 1826
91740-80049/50/51/48 -- Rev. 1913
91740-80064/65/66/48 -- Rev. 2003 (bad ROMs; withdrawn)
91740-80067/68/69/48 -- Rev. 2003 (good ROMs)
91740-80070/71/72/48 -- Rev. 2540 (adds 7974 loader; no DS change)
(The first three ROMs in each entry are the microcode ROMS; the fourth is
the CBL ROM.)
Pages 3-104 through 3-136 of that document give the firmware revisions of
all of the HP products then in support.
Anyhow, looking at the ROMs and dates, I suspect these
are E/F
microcode only and would not work on the 21MX.
All of the above are E/F-Series only.

Thanks a lot. Anyone wants me to dump the DS/1000 rev 1826 ROMs or are these already
available?
What?s the CBL ROM? The one that?s on the cable interface card?

To my knowledge, they are not available.

interface card?
No, it's a boot loader ROM ("CBL" is Communications Bootstrap Loader) that
will load absolute programs across a DS/1000 link. So it's one of the
small PROMs that mount on the CPU board and that is invoked by the front
panel IBL button. It's used to bring up a memory-based system node by
loading the OS from a disc-based node across the link.

These are the original DS/1000 ROMs (date code 2003) without the 7974
loader extension. That was added in 1985 (date code 2540) with the
80070-72 set. The 12992-80011 ROM loads the extension from the DS/1000
ROMs into memory for execution.
any help would be appreciated.
Contact me off-list if you still need copies of these ROM files.
