3) Are their any driver chips that will allow me
to input a digital value and get the correct corresponding Pulse Width
Modulated output to drive a hobby servo like Futaba, etc.?

There is probably no ready-to use chip to control a servo with a digital
value. But you have two solutions :

1. Try to program a pulse width modulated signal output. You need a fast
"brain"...
2. With an digital to analog converter and a 555 chip, you could
probably convert an 8 bit signal to the right pwm... Didn't test it
though.

For the first solution, I've already made a simple servo tester, which
use a standard printer port, and a windows proggy (sources included).
You can control up to eight servo's with one parallel port...

Look at : http://users.swing.be/philippe.jadin/servoen.htm

Good luck !

Hi everyone. I'm new to this site and was wondering if anyone has the information I need. 1)Who makes the UCN 5804 Uni-polar stepper driver and is it still made? 2)Where is a good place to find a wide selection of hobby size stepper motors on a (...) (25 years ago, 18-Sep-99, to lugnet.robotics)
