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.
