To my knowledge, they are not available.

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.

Re: Hp 21mx loader rom set
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?

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. -- Dave
RE: Hp 21mx loader rom set
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.
