Arduino Board as HP-IL device?

[Jurgen Keller]

I don't know much about electronics, however, as you can implement nearly anything with an Arduino board I'm wondering if you can also make one acting as a HP-IL device. I see two basic variants:

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?
