Sorry for the delay, I had to find the CP/M module first :-)
You only need one floppy, here is the directory:
[ Volume ]: HPCP/M
Name Type Bytes Recs
CP/MSYS DATA 256 1021
Autost PROG 256 5
CP/M BPGM 256 25
Autost is a Basic program:
10 PAGESIZE 24
20 PRINTER IS 705
40 LOADBIN "CP/M"
File CP/MSYS is the CP/M filesystem (your DRIVE A). If you try to use the native COPY utility, you are likely to corrupt this file. You have to use the CP/M PIP command.
The floppy behaves like typical Autost floppies: if the
floppy is in the drive, the system loads Autost, runs
it and boots into CP/M, if the floppy is inserted after
the 87 boots into Basic, you can still LOAD and RUN the
Autost program and boot into CP/M. If you press [SHIFT] RESET
you get back into Basic.
Once CP/M is up, you can do a DIR and see the files that
exist inside the CP/MSYS (filesystem) image.
BTW, if you happen to have the software for the HP 82900A
terminal emulation co-processor, then this should be usable
with the CP/M module, since the actual hardware card is the
same for both systems. Unfortunately, I do not have this S/W.
