Hey all, I just had a question about how many variations there are as far as NES decks are concerned. I have a pretty low number S/N N0481951. the top of the NES is very smooth compared to my others (the others have a bumpy texture) and the bottom has different stickers on the bottom. There is also a No,1 cast on the bottom inside the ridge by the expantion cover. I also had another deck with a higher S/N with different labels (similar to what you would see on an SNES) as well. Have I gone too far off the rocker here in noticing these things???

No, there are many revisions. Does yours flash blue? Blue was the standard flashing colour early on and if it flashes blue it has the best chance of being compatible with all unlicensed games. Later on, when NOA started tinkering around to stay one step ahead of the renegades, the screens started flashing pink, yellow, etc. I don't know if anyone on the net has ever decided to document any of this, though, or figure out which serial numbers match up with which revisions. Anybody else?
