Poor Man's PIC Programmers (Serial, Parallel)

Professional PIC programmers are expensive. If you have limited budget, you can instead build your own out of less expensive parts. Note that these circuits will need either a parallel port or a serial port.

The following chips are supported: 12F629, 12F675, 16F627, 16F627A, 16F628, 16F628A, 16F630, 16F648A, 16F676, 16F72, 16F73, 16F74, 16F76, 16F77, 16F737, 16F747, 16F767, 16F777, 16F83, 16F84, 16F84A, 16F87, 16F88, 16F818, 16F819, 16F870, 16F871, 16F872, 16F873, 16F873A, 16F874, 16F874A, 16F876, 16F876A, 16F877 and 16F877A.
