Which was the one that used that rectangular connector often mis-called
the V.35 connector?

I have a thing called a Ferret here. It's a combined breakout box, RS232
to current loop to parallel interface, strip printer, EPROM programmer,
Z80 computer, etc. The parellel interface can be set up to be either Centronics
or Dataproducts.

Some of the old Daisywheel printers, both Diablo and Qume had an interface
with over 20 data lines. You specified print wheel position, amount to advance
the carriage, etc on separate lines.
