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)
Thanks, Fred. The docs give the pinouts on the card-edge, so a cable
should be no problem.
The other 34 pin is for external floppies. It should
be possible to
identify which 34 is which by proximity to the disk controller.
Piece of cake -- thanks again.
"expansion bus" On the model 1 it was 40
pin. Did they change to 50 on
the 3?
I don't know -- I wonder why this is not shown in the docs?

A trivial gotcha if you're not paying careful attention:
The numbering of the connectors of the cardedge is even numbers on one
side and odd on the other. Thus 1 is opposits 2, 33 is opposite 34. But
the numbering on the "centronics amphenol" ("blue ribbon"?) is 1-18 on
one
side and 19-36 on the other side.
I don't remember whether the external floppies, which are the third and
fourth floppies, are expected to be jumpered as drive 0 and drive 1, or as
drive 2 and drive 3.
