After some time of developing and debugging I am now happy to announce that I have HP-IL emulation up and running ...

Amazing job Meindert. Just as I've noted for Thomas' related project, this is really impressive, an amazing accomplishment. It's quite remarkable to have created a module/device that provides so many powerful and useful features, 41 users of all types will want and appreciate one of these, we look forward eagerly for updates and a hopeful announcement that it will be made available.

And of course thanks are also due for other contributors, principle among them: Andrew, Christoph, Jean-Francois, and Thomas! Such work is never done alone, so the work of prior giant contributors is important and due.

Mindbogglingly cool.

We really would!
Thanks to the team for all the research.

It can trace the bus traffic and dump to USB and can also drive the bus and hence emulate a module or modules. It can also enter programs by pressing keys on the keyboard. There's a small OLED display that mirrors the LCD. It is very much a work in progress, so for instance, the entered programs aren't quite right and I've only emulated the MATH module.

Sniffing then extending an HP12C bus would make it interacting with the external world?
