HP-75 I/O Utilities

[Vassilis Prevelakis]

Anybody has the programs included with the 00075-90122 HP-75 I/O Utilities Solutions Book?

I'd really appreciate receiving a copy

Thanks

I have the HPILCMDS program, which is the main (if not the only) program from the I/O Utilities solution book.
The problem is, unlike all the other solution books, which were BASIC programs, this is a machine language LEX file. I am not sure how you'd transfer it to the
HP75 other than reading it from a magnetic card or a LIF disk or tape.
If you can think of a way to load it, I can see what I can do.

Unlike the HP-71, you can't key in a LEX file into a
bare bones HP-75. You need either to download it from some
mass storage media (mag cards, tape, floppy, HPIL device,
etc), or else you need a well-known loader BASIC program,
but unfortunately this program requires some version of
the PEEK and POKE keywords, and that aren't on 75's BASIC
but must be provided by some LEX file, PEEKPOKE.LEX for
instance.

This obviously is going in circles: you need a LEX
file to be able to key in another LEX file. The point is,
perhaps it's easier for you to get some version of the
PEEK/POKE keywords in the first place.

If you do, you can then key in the loader BASIC
program, then you can key in other LEX files directly
from the keyboard, assuming you've got them in printed
form in hexadecimal format, many are available in that
format.

The corresponding BASIC programs for an HP-71 are
called MAKELEX (to key in a LEX file) and DUMPLEX (to
generate a hexadecimal dump of a LEX file already in
memory). This will work on a bare bones HP-71 because
it does have usable PEEK and POKE already on its
standard BASIC in ROM, but most unfortunately, the HP-75
does not.
