IIRC, #26-1401 It is basically straight through, and can be made by
crimping a card-edge connector on one end of ribbon cable, and a
"centronics" amphenol connector on the other. Sorry, but I don't remember
which direction to offset the cable (for the 34 v 36)

The other 34 pin is for external floppies. It should be possible to
identify which 34 is which by proximity to the disk controller.

"expansion bus" On the model 1 it was 40 pin. Did they change to 50 on
the 3?

I'm going from memory. It's been more than 5 years since I TRS-80'd.
