ahh then something is really wrong on my end of things. I have tried to programm both the 12f629 and the 16F876A, it fails on verify at the first adress and comes back with the value 0000(h)
Do i need to connect the vdd (not from ICD2) to mclr or something like that?
VDD is generally a 5V supply, yes you need to provide a stable 5V supply to the VDD pin on the PIC.
If you plan on working with PICs you should consider a decent programmer, they're pretty cheap these days. You'll need a HVP programmer for your 12F629 anyway.
Yeh im going to buile a ICD2 clone (stolz schematic and adding header for USB to be abel to expand later on) but i need to programm my 16f876A. I have found the correct bootlader for it (Microchip dont have it in MPLAB, as far as i know). So problem beeing flash the bootlaoder inn to make the clone. Any ide to help me
