The only thing that springs to mind, is the "credit card" organizers
that have calculator key type buttons. There are a few that have a
fully QWERTY keyboard, though not the Fn-keys, etc. Some are
almost the right size -- a matrix printed on a PC board could go
underneath, and the keys usually have conductuve rubber underneath.
That would make it "work."
The matrix does not require discrete *buttons,* but only contact
between 2 conductors. :-)
Casing -- we're talking custom work. You could always hack the
casing from the organizer, though that's hardly ideal. There are
always options though. Wood, custom plastic, fiber/epoxy, metal,
and probably a few others I'm forgetting.
Wiring -- there's a simple bundle of wires that comes out of the
SIMM stick, and the cable could probably remain. Alternately,
it's just a serial data stream, which means it could be hacked to
be wireless, whether it would be IR or radio is immaterial.
