RE: Arduino Board as HP-IL device?

  1. An Arduino board with an USBSerial adapter and a PIL-Box; this seems to be the easier variant as the IL signal processing is already done inside the PIL-Box.
  2. An Arduino board which connects directly to an IL interface through the analog pins on the board. Not sure if this is really possible but there are analogRead/Write functions that might be used to read/write the IL signal.

The Arduino board might be battery powered. Therefore, you would have a small battery powered device which might, for example, serve as an HP-IL mass storage device. The benefits I see are:
  • you don't need to startup your computer to save/load some programs to your IL capable HP calculator
  • you could easily exchange programs on SD cards
  • it might be quite a mobile solution to take with you
  • it might be a path to many other exciting applications
  • ...

Anyone who can assess this idea? Is it possible to implement that with "reasonable" efforts?
So far, I am using a raspberry PI4 (not arduino; however, small size). On the ToDo list is now to make it headless (prio C for me); however, a terminal output is good.

HP71 4TH/ASM & Multimod, HP41CV/X & Nov64d, PILBOX, HP-IL 821.62A & 64A & 66A, Deb11 64b-PC & PI2 3 4 w/ ILPER, VIDEO80, V41 & EMU71, DM41X, HP75D
