The 'pulse generator' is a pulse width modulation function. Many
microcontrollers have PWM functions integrated in them. That's where I would
start. Check out PICs and AVRs. You'll probably even find application notes
on PWM for servos.

Assuming you are talking about the model airplane hobby types of
servos, there are a number of servo control boards available in
varying price ranges. I've made a fairly cheap and simple
computer controlled servo control setup using the Kronos Robotics
ezservo control chip (~$7). I use it to control the servos in my
homemade pan/tilt webcam (bottom link). There are other "servo
tester" kits that use resistor pots and 555 timer chips to
control the servos instead of using programmed chips. Google can
locate those. I've found one free windows program that can
control servos from the parallel port, but it wasn't practical
for my webcam setup.
Got a '240 logic chip, some caps, and resistors? Check out the schematic
for the "Servocore" circuit which is part of our "Bicore Experimenter's
PCB". Free documenation online. Check our the "resources" link on the
main page for the PDF.
