To operate the PMS:
1. Load the PMS commands into your HP-75.
Do this by reading the
magnetic
cards supplied with the PMS.
This needs to be done only once so long as
the HP-75 memory is maintained.
2.
Turn the HP-75 off, plug the PMS into a port in the HP-75 , then turn the
HP-75 on again.
3.
Execute BUILD to initialize the desired memory bank and to set
the
ROM
ID.
4. Write, or copy, your program into the HP-75.
*
5. Execute ROMSIZE to determine the size of the program in
the
HP-75
you
wish to copy into the PMS.
*
6. Execute ROMAVAIL to determine the availability of sufficient room in the
PMS for your program.
7. Execute COpy to read your program into the PMS.
Note: It is possible to assign
the
same
name
to
your program in the PMS as that
of the same program in the HP-75.
If you
do so, and you run the program, the HP-75
will run the program in
its
own
memory
and
will
ignore the program in the PMS.
8. To edit your program, read it back into the HP-75 using
the
COPY
com-
mand, make your changes, and return it to the PMS.
9.
Repeat the above steps, as required, until you have loaded a maximum
of
eight programs and files plus one LEX file into your PMS bank.
*10. Mark files PRIVATE, as desired.
At any time during the above process, your program can be tested
by
running
it just as you run any program in the HP-75 using a plug-in module.
After you have developed and fully tested your program in
the
PMS
and
are
satisfied with the results, you may elect to have Hewlett-Packard create your
permanent plug-in module.
You should contact Hewlett-Packard for further in-
formation on how to proceed.
Refer to appendix E for the operational limitations on the use of the PMS and
permanent plug-in modules.

Optional step.
