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?
