The places I'd look are first the RS232 connection. The fact that the canon book works on one machine doesn't mean it will work on another. As well as the data lines, there are handshake wires that need to have the right levels. He said that he'd single stepped the code, what were the results of that? what did it do or not do right?? Dwight It just goes crazy as the Prom was not burnt correctly Bob Turns out that the Problem is that the Data I/O System-19 I am using doesn't want to load the Hex file as INTEL. It will only load a File if it is flagged as BINARY and that doesn't give a proper code Image. I am trying to get a fellow to see if his System-19 will load the file and burn the 2708 Properly then I can get mine Fixed I HOPE. I also have been Re-Erasing the EPROMs as I go along. Bob
