I have been using this same setup for a few years now it works great.
Quoted from NJGecko:Nothing secret about it...

The biggest thing I learned was to remove the labels from the existing ROMs so they would erase. I kept taking them, plopping them into the eraser, trying to burn them, and got errors. Literally an hour's worth of head scratching until I thought, hmm, UV...maybe this label is blocking it. Yeah, that made my life a LOT better
To be fair, I did hunt and peck and found a used programmer because I'm a cheap SOB. So the used one ran me around $80 shipped.
