   I don't understand why your mouse doesn't work, unless it has something to
   do with what revision your //c is.  I seem to remember that certain
   versions of the //c map the mouse port to slot 7 rather than 4...

The behavior in PCS is quite strange.  When I wiggle the mouse and then
stop, and the cursor continues to move smoothly in some direction which you
can sort of influence by moving the mouse.  Unfortunately the cursor never
stands still, and the mouse button doesn't work.  I wonder if a //c mapping
the mouse to the "wrong" slot would act this way.

The mouse works fine on the Mac.

Can you suggest an experiment or two to diagnose the problem, perhaps to
figure out the ROM version and what "slot" the mouse is mapped to?

Thanks for the code!
