Up is irrelevant, wide side is irrelevant -- Borg, ST:TNG

If I were you, I'd look for a pin #1 assignment and go at it that way.  DB-25's
are pretty common, most of them have the full pin assignments listed on the
plug (grab a magnifying glass and a flashlight), as for the centronics
connector, they are either labeled, or you will need to find a book that
lists the pin assignments.

BTW, doesn't a centronics plug have 50 pins?  25 < > 50 !!!
