programmer hardware will, if it guarantees >= 12VPP prog voltage.
PIC16C84 programming software will not. Algorithms are different.

there are many programs that program C71 with and C84 programmer hardware

You can build ProPic and use software from TATO computers,
or you can build any DIY programmer and use our PIP02 software.
