I'm having trouble with the eprom programmer, when i blackcheck it, it says that it is empty, so i proceed to write the rom. While writting the rom it starts making a weird noise like static noise, after 3 minutes it starts verifying and then it gives me an error, i restart the cartreader and verify again, but still says that there was an error, and if i blankcheck it, it says the eprom is empty. I set both buttons to down position for writing, do i need to change them to the up position when Reading? This is how my adapter looks like.
Edit: Forgot to mention that i didn't solder the 22uf tantalum capacitor, probably they will arrive on monday. Can i damage something by not having that capacitor?
