A rare bird

* “Keying” refers to the “bump” or “groove” that is intended to prevent the wrong plug from fitting into the wrong socket. There are currently three different 10-pin keyings: “NONE” (no bump or groove at all), “small” (tiny groove at the top of the HP49G serial port, or the same-sized bump on corresponding plugs), and “LARGE” (a wide bump or groove, intended for palmtop use only).

** “Ferrite bead”: the strange black lump in some cables, near the calculator end. Its only purpose is to reduce the amount of radio frequency noise emitted by the cable. If RF noise is not a problem for you, but the lump annoys you, it can be easily removed by simply crushing it with a pair of pliers. It is not electrically attached to the cable at all (it merely surrounds it) so removing it is no problem.

If you have any HP cables or adaptors not listed here, please let me know!  Thanks to Richard Nelson, Ralf Fritzsch, Raymond Hellstern, Cary McCallister, and Glen Kilpatrick for submitting additional information.
