Hello Miquel,
I'm using the same combination for programming the 16F628. You can use the
ICPROG software. The only thing you have to do is with a short cable connect
GND, MCLR (RB3), RB6 and RB7 from the JDM-programmer to your circuit in
which you are using the 16F84. The only thing you have to do is isolating
MCLR, RB6 and RB7 from the rest of your circuit.
