I have the
thing opened up right now. There are 24 DIP switches,
three banks of eight, labeled SW1 through SW3.
Yikes! That's a lot of
combinations to run through! :-)
Well, yes. :-)
The pc board is only two-layer, though, just front and back. I may try
to trace where the switches connect to to see which ones are plausible
guesses for what I want.
There's
also a momentary pushbutton switch of no obvious function
(inaccessible with the cover on) labeled SW4
reset, to allow an engineer to reset
the pad without killing the
power all the time?
That would be my guess; it is placed right next to the chip I suspect
of being the CPU.
and a
six-contact card-edge connector of equally obscure function.
My tablet's got
both a pen and a puck; maybe that's a pen connector?
It could be, but the puck is connected with an RJ-11-style plug and
jack, which jack could equally well be used for a stylus if the
interface is sufficiently compatible.
