Hi again, thnx for the link gayan, it did helped me understand more about JDM, but im still unable to get a 16F84 programed, i just cant get pass through 0000h error, i tried enablin and disabling stuff from here and there but i keep gettin the error, i tested the Vpp and im getting the correct 13v and this is starting to frustrate me, im gonna program the chip tomorrow on the school with microchip's pic start plus and make sure that its not the pic itself the one causing troubles and i will also try to use my programmer in another desktop computer, i would really appreciate any new ideas on what should i do.
BTW try using winpic 800.It auto detects the PIC first. So we can confirm your PIC or the Programmer working or not.
If you are in a hurry you can build that the simple JDM programmer it works fine with many PIC's.
Is it 84 or 84A?
Can you tell the part numbers of the transistors in your Programmer?

Hi, again thnx to every1 for helping me out, im sorry about the delay between my posts and replies its just that im on the last week of school so im spendin most of my time there.
Im using a JDM programmer i bought as a kit already assembled from the store and using a PIC16F84A-04 , component list are as follow:
Q1,Q2= BC547B
Q3(the one near the electrolitic cap)= BC558B
I cant read all the diode part numbers theyr kinda faded, but i could see there are some 1N4148(3 or 4), there are no IC's on the board, there is one jumper thing that has to be set in position 2-3 for the 16F84 according to the manual, oh and 1 more thing is that there are 2 diodes just above the 10k resistor if watched from the image i posted, and theyr soldered on inverted-paralel(something like a diac) one over the other and the holes for d8 are empty, it looks kinda bad to be a purchased kit but i tested with the ohm meter and they seem to be the same nodes, i have to go school now so i wont be able to post until night, i really appreciate all the help from every1.
