Hello, I've ordered some PIC16C711-Devices thinking they are compatible with the PIC16C71 ones. But I can't programm them with my old PicStart16B1 programmer. I've got something stuff into one device, but it is not programmed corectly, the other devices I tryed are left blank even If I try to programm them many times. Only the Config Bits are programmed (I can see the changes if I read them out) the Programm Memory is still 3FFF. I can't understand how I get something wrong into the first one on nothing in the others, but I can still programm my old PIC16C71 EP-ROM-Device. I had to notice to that MP-Lab don't support my Programmer and I can't find any new updates for my dos-software, so I'm a little bit angry about microchip, the programmer is not yet two years old. Any Tips? Bye Ingo
