Hallo,

I have a problem with the Pic 16C84 protect chip.If I use the system
describe in the net to remove
the protection (Vdd +13,5 and reprogramming OFF the Code Protection)a lot
of Chip are DEAD!!A few
there's still a program but if it's impossible read or write a chip.And
others are KO!I ave see the page
of Interesting Device from Justin Farrell and there's a PIC2PIC
copier/busters vithout PC and very very
simple.You know this system?You know another system simple and secure?
Tank you for your interest.

Best regards                      Lazzeri Marco
