I had a look last night and do have a couple of old serial mice that
I could butcher the decoder circuit from.

You don't need to write a device driver just to interface the wheel
unless you are going to integrate your jog dial into the OS itself.
If you just want to do something "programatic", it's simply a
question of (say) using a the Visual basic serial control and reverse-
engineering the serial protocol (I imagine google would help with
this).
If you really do need to write a device driver, then either get hold
of the Microsoft Developers Network DDK (MSDN DDK) or trawl the MS
site for the DDK (although I *think* they withdrew it about 6 months
ago). I warn you, it's a big job.
