I was assuming the connector itself was fixed and the only issue was which
way the 5 signals get connected to the 5 pins.  In that case there are 5
choices for the first pin, 4 for the second, 3 for the third, two for the
fourth, and 1 for the fifth.  That comes out to 5! = 5 x 4 x 3 x 2 = 120.

Of course this points out that we can't even agree on the connector.
Personally, I put RJ-12 connectors with the ICD-2 pinout on my debug boards.
That of course works with the ICD-2, which is a big plus.  In addition, one
could easily hack up an RJ-12 cable to connect the other end to whatever you
wanted.

I just got boards back today for a hobby version of my programmer that
brings the 5 programming lines out to labeled pads, and ICD-2 connector, and
of course still muxes them as appropriate to the ZIF socket.  I deliberately
made this board all thru hole for easy do-it-yourself building.  I'm
thinking of just making the bare boards available with schematic and parts
list.
