Personally, I'd move the IEEE-488 Card up to the Input/Output category.

The IEEE-488 card is a specialized parallel interface for communicating
with scientific equipment.  The interface is also known as IEC625, GPIB,
or HPIB.  GPIB is General Purpose Interface Bus.  HPIB is Hewlett
Packard's version.  I recently purchased an Apple IEEE-488 card but
have not used it yet -- I just acquired the official documentation
and located some sample code in 6502 and Apple Pascal on one of the
Washington Apple Pi disks.

Since you made reference to the cassette port, I would see no harm in
discussing the game port (its signals, connectors, etc.).  I have some
materials on this from a document I wrote about my 1994 KansasFest
session.
