Paul, I recently bought an adapter from Digikey that is used to program PLCC packages. It is a 40 pin DIP to PLCC package adapter. I used it in the PSP and it worked great! Digikey's part number is 309-1039-ND It cost $115.00. Programs the PIC16C64A, 65A(B), 67, 74A(B), 774, 77, F874, and F877 in the PLCC packages!!!
