TLVP only supports a few PICs. I think it is also not so safe to use. People have fried their serial or parallel ports on the motherboard using simple circuit like TLVP when hot plugging. Again a PIC programmer without a PIC on it is not worth considering in the long run. People end up spend more time on debugging the programmers than they spend on their project.

So it would cost me an additional ZIF socket and a board to put it on. I agree that the cost is low ($6 at most, maybe) but it is there. Thank you for all the information! I decided that I'm probably better off building the TLVP from Byron A. Jeff.
