if the EPROM stored the configuration for an FPGA you have a whole different problem). (Same is true for whatever other microprocessor was used. If that's a Z80 microprocessor (for example), there is such a thing as a Z80 program, which you may be able to disassemble (read the EPROM in the burner, write out as a hex file, probably INTEL HEX format), then run through a disassembler program to generate a source listing in Z80 assembly language.Īt this point you may get lucky - a "hex dump" of the file, separate from the disassembled listing, will probably show you some ASCII strings - text that give you some clues what it does. Any such information you can add to the question may help, even a good quality photo of the PCB. you need to know what the EPROM supplies its data to. There is no such thing as an "EPROM program".
