Dave,
Yes, my unit came with the front cage basically full with the DCPC, Mem
Protect, MEM, and 640k HSM. the back cage was stripped to the point that
several grounding straps were ripped from the boards on removal. I've got
a 12531D board on the way, and will be doing more reading on interfacing
with the/a emulator.

I'll need to do more research to see if the I/O boards for these drives
would be a good starting point to connect the USB drive emulator or
just try another serial card and interface with it. (and a bootloader to
load HP IPL/OS).
Presuming the standard set of front-plane cards (12897B Dual-Channel Port
Controller, 12892B Memory Protect, and 12731A Memory Expansion Module) are
present above the memory cards, then another alternative would be to run
the HP RTE operating system. That would require these I/O cards:
- 12539C Time Base Generator
- 12821A HP-IB Disc Interface
- 12966A BACI or 12531A/B/C/D TTY or 12880A CRT Interface
...plus a PC containing a GPIB card to function as the disc drive running
the HPDrive emulator available here:

RTE-IVB and RTE-6/VM are multi-user disc-based OSes. An assembler and
several language compilers that run on RTE are available as part of the HP
1000 Software Collection available on Bitsavers.
