NEC!
And it was only sold in the US, so I wasn't able to get a datasheet from
NEC-Germany.

At the moment I've build a pcb (with the Atmel AT89C51 + Midi-In/Thru/Out)
to control all 303 pots by midi-controllers. The board is ready, I'm only
working on the software. This board has another connector to a small
external pcb or a 2x16 LCD. Later I want to use this "open port" to send
notes/accent/slide to the 303 audioboard.
