Don, Joe,
I might be able to help both of you!
I believe that I have a manual for the HP-IL RS323 device somewhere, probably
also the device itself. I'll check and revert.
I also have an old HP 110+, the HP-IL printer that goes (went) with it, a HP-IL
floppy drive (720kb), and a HP-IL GPIO device (General Purpose I/O).
I'm willing to trade the HP-IL RS232 device for (almost) anything for the
HP110+, S/W, firmware, or the memory expansion board. Suggestions, please!
Thomas
