This article is from the Apple II Csa2 FAQ, by Jeff Hurlburt with numerous contributions by others.
If you have a an RS-232 interface (2400 or 9600bps) you might consider a
kit from Lynxmotion ( http://www.lynxmotion.com ). They sell various robot and
robotic arm kits that utilize hobby R/C servo motors. Scott Edwards Electronics
and several other companies sell devices that allow you to control up to 8
servos per board.
You'll have to write all of the software yourself (sending commands to
identify a servo and a position value).
