I'd like to mount a DB25 parallel port on the back of my IIe with a
short cable to the printer card similar to what I have done with my
SSC card.  It is a standard part?  Hints on where I can get one?

A DB-25M/F is about as standard as they get.  What isn't necessarily standard
is the pinout on the card itself.  Which adapter are you using?

I was afraid of that.

Perisoft, Inc. Printer Link.  I have no docs or pin-outs either.

Do you have the original cable from the printer card with the Centronics
connector at the printer end?


Found it.


If you have that, and a multimeter, it should be a few minutes with the
meter, a pencil and paper, and you'll know the pinout at the interface
card end.  From that, you know the standard DB-25 pinout, so you can
make/acquire the right cable.


Yep, I figured that would be the worse case scenario.  I'll order a
DB-25 female with solder cups.  I'd prefer to not butcher up the
original cable, so, any pointers to a 20C ribbon cable with connector?

PCs with floppies had such cables.

I presume that you intend to wire the socket so that a conventional
PC printer cable will work to connect it to a printer.
