[Coco] Arduino as a Mouse/Keyboard interface?

[Frank Swygert]

The new Arduino Leonard board has direct USB interfacing, and a USB 
keyboard and mouse can be plugged in and translated. Wouldn't this make 
a great replacement for a Puppo or similar PC keyboard adapter for a 
CoCo? I'm not really a programmer, but it seems that it should be easily 
doable from what I remember about how the Puppo adapter worked. Would 
just take writing the correct program for the Leonard and making a cable...
