Yes. Just use the "servo.icb" and "servo.c" libraries that are
distributed with Interactive C. This will convert the Handy Board's
digital input 9 sensor (which is really a bidirectional counter/timer
pin) into a stable servo control line.
You can get the servo power from the Handy Board's regulated +5v
supply, though this isn't the best solution (the regulator will get
mighty warm). Taking a tap from the +6v point inside the Handy
Board's AA battery pack should work nicely.
