Hello, I am planning to replace a 16F84 with a 12C508 as well. I was just wondering if is possible to use a programmer that was made especially made for the 16f84 (kit 84, kitsrus.com)? I was think that I all I had to was simply map the proper pins made for the 16f84 down to the 12C508? I have the pdf schematic for the kit if anybody wants to help me. Thanks. Sep S.
