The older Logitech serial mice used the Motorola MC68705P3S, which is a CPU
(8 bit) with EPROM.  Seems later on Logitech went to a custom version of
this chip, rather than programming an EPROM for each mouse.

These chips have apparently gone through several revisions, too.

I've found a local surplus store seems to have hundreds of boards and cases
for Logitech mice, both serial and bus.  They also have cables.  Now if you
can find a ball, and for the serial, the CPU chip...
