Well this  particular unit is connected serially via
a serial to parallel converter since its input is 
designed to interface with the  centronics port
of an older PC.  I use the bitbanger on the coco
side.    The connection is open loop, there is
no feedback of positional data.   The spyder
I plan to use has real servos on each joint.
 
When I start I will look into posting my results
either here or on a web page.   The main holdup
right now is money.   The dern thing runs about
$800 bucks but I have been planning and saving
for awhile now so it should happen soon.
