This and a lot more is documented in the assembler ROM.
It has a wealth
of information. Enough, in fact, that I've been toying with writing an
emulator for it, but of all the defunct old computers, HP is one of the
few that is still in business and would probably seriously care if
someone ripped their ROMs for an emulator. If somebody thinks HP might
not care, then I might consider writing the emulator.
They might care... but regardless, you could do what someone else
did in relation to the HP48... they wrote an emulator, and simply
told people that they didn't provide the ROM images, that was up to
the user of the emulator to provide -- by having an HP48[GX] from
which they could download a copy of the ROM to use. The person
even provided a copy of a program which would assist in down-loading
the ROM image.
