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.

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.
