I have an Epic Plus // port programmer with the ZIF 8 to 40 pin adapter.
Todate it has worked without problem on many different chips from 12c671 to 16C774. But I am trying to program a 16c770 and it will not program. The program voltage comes on and it appears to be working but after programming the chip is still blank. If I change to a different PIC, even with sme settings it programs OK. I have tried different 770 chips and different settings without any luck.
Any ideas would be welcomed
