I don't recall if there is one or not Roy. I have one of those, and it uses
at least as much I/O as a serial port. However, if space for that can be
found in the coco3's limited I/O space, the driver itself should be fairly
easy, just put the read data into the already designated mouse packet. I
believe it can also do mouse clicks but its been 20 years since I played with
mine so that may be in error. Very faint, probably moldy memory tells me its
resolution needed another 1 or 2 bits of width both ways to reach what the
coco3's gfx can do. That makes the data, for h position more than byte wide,
and that may be why I got sidetracked and quit fooling with it.

Q: Why is it that the more accuracy you demand from an interpolation
function, the more expensive it becomes to compute?
A: That's the Law of Spline Demand.
