It rarely matters. any hardware that can program a 16F84 can program a 16F87X or 16F62X part. The only tricky part is the programming software. Since most every part has more program memory, the programming software may run into trouble if your program exceeds the original 1K memory limit that the 16F84 has. > > The attachment contains the circuit of it, maybe you can have a look to it > and see if I still can use it. > If not maybe you know a different circuit (I do prefer COMport circuit). No attachment in either post. I developed the TRIVIAL LVP Tail style parallel programmer precisely for simple programming tasks.
