Well ive done everything, i used the slowdown program and that didnt give me an error with the verification proccess, and the read process went through i guess. .since the chip is blank, but i didnt get any errors just put it like that. HO WEVER, i still cant program anything. I tried adding a seperate 12.10V supply t o the reset and swiching it i can not get this thing to work. Has anyone ever a ctually got this to work than can really help me?? I would just buy a real programmer but im a begginner and dont want to waste a f ew hundred on something that i may not use on a permenent basis. mike m.
