Looking for data sheet for Intel N82930A3

[Ethan Dicks]

I'm taking a stab at reverse-engineering a Toshiba "intouch" module
DT-1003.  It's been
brought up here before (I got it from a list member).  What is slowing
me down a bit is
the inability to find any data on the CPU... an Intel N82930A3.  If I
understand things
correctly, it may be a variation of the 8051 microcontroller packaged
up with a USB core.
>From tracing leads so far, the USB connector does go right into the
CPU, supporting
the suspicion.

If I can't manage to unwind the protocol (it's about 10-11 years old
and not supported under any "modern" operating systems), I'm
contemplating removing the CPU and building my own thing to drive the
T6963-based display and read the buttons/IR port/rotary encoder. 
Naturally, it makes sense to spend some time just trying to blow
packets at it first.

Thanks for any pointers.
