Hi,
   How does the 1350 mouse works?  Can it be possible to convert that
mouse in a more or less proportional mouse, by using the LightPen
interrupt?

The way I think it could be is that you rewire the outputs, so
everytime the mouse moves a certain distance, it will generate an
interrupt, the same way as you generate an interrupt when you press
the joystick button on port 1, and the Lightpen interrupt is enabled.
So, a driver can be writen, that will enabled by that interrupt, and
update some counter in memory.

Is this idea possible, or I have a wild imagination?
(BTW, I have no idea how the 1350 Mouse works, so this ramblimgs might
be full B.S.)
