I've got a problem trying to program 12C508 PICs with my PIC 1a programmer. After wiring up the appropriate 8 pin adapter required to accommodate the 12C508, I get an error every time I run the PIC12CR.EXE program. It finds the hardware, asks me to insert a PIC into the socket and when I hit enter, it immediately says PROGRAMMING ERROR and quits. It writes nothing to the PIC at all. What's going on? Is there an additional hardware change I need to make? Adios, LarZ ------------------- TAMA - The Strongest Name in Drums --------------------
