the good old DB-25 pin connectors. Case in point, the

Actually IBM got that one
right. DTE (e.g., computers, printers) are
supposed to use the male connector, and DCE (e.g., modems) are supposed
to use the female.
Instead, IBM used the
female one for the parallel printer connection!!
Using a DB25 of either gender for a parallel printer connector was
brain-damaged.
