If that's true (sounds right to me), then maybe this will be useful:
I did a tiny (practically free at OSH Park) PCB a while ago that adapts
10-pin ribbon cable to a DB25P (wired as DTE). It can work with a Berg
Unless you need to make a lot of them, I would have tought it was quicker
to crimp a ribbon cable to the Berg socket, splig the other ind into
individual wires and solder thsoe to the DB25 (or DE9) connecotr than to
etch and drill the PCB.
