 +1 Good Answer/Helpful		 #145695 - there's much more in an EPROM programmer...
Responding to: ???'s previous message
... than just a microcontroller. It's relatively easy to generate the control signals, the devil is in the details - the high voltage power supply has to be stable with relatively heavy current pulses drawn by the EPROM under programming.

For inspiration, try to google for the original intel's BASIC52 - it was capable to "burn" EPROMs on it's own; in the manual, there's a schematics and the sources are available, too.
