I would be _very_ suprised if it was a 'raw' interface like QIC-36. Since
the tapes are pre-formated, and have various markers on them, you can't
just write an aribtrary bit pattern ot the tape (you risk overwriting the
markers), which a raw interface would generally allow you to do.
It's much more likely to be a 'formatted' interface. With a 50 pin
connector, my first guess would be QIC-02.
