Most 4070s have a custom parallel interface (which is not too hard to
link up to other things, actually). There is a serial card for them which
fits inside the case and gives RS232 and current loop interfaces, but
it's _very_ hard to find.
I have this card. It is a while ago since I last looked at it, but iirc
it didn't look too complex. If anyone wants to reconstruct this card,
feel free to contact me.
