This is an instance where you seem to have more time than money. Typically to program an EPROM you need a programmable voltage source and it's helpful to have a good timer. Lastly you need a way to get the data from the file to the EPROM. A PIC can help with all these tasks: programmable voltage: Check out an article that Steve Ciarcia did for BYTE magazine (about 10 years ago) where he built an intelligent serial EPROM programmer. You may not want to use the whole circuit (you can) but the LM317 based programmable voltage generator is definitely the ticket. Presuming a high voltage power supply (17-25VDC) is available, the programmable voltage part can be built for less than $5. The PIC can then control the voltage. Timer: PIC's have real good timers for the 0.1ms pulses required with most algorithms. Data transfer: Most any PIC can be programmed to read data from the serial port. It is also possible to use the parallel port to transfer data. You can put one together for maybe $20 and a lot of effort. BAJ
