Well the action of the I/O lines has to be controlled by the QL driver -
the pIC has no intelligence re this port - it just works to outside
instructions. It should though be trivial if the clock is async.
The hard part might be the driver - which will need to access TTs mouse
registers. Beyond me certainly.
It would certainly be nice to have a mouse with sH LITE, and I will fit
the connector to all future production.
