I can't seem to find a list of serials much like that of the N64 and SNES being accumulated. I've made note of what I have including motherboard revision, video encoder and other notes. If anyone is willing to crack theirs open I'll gladly add it to this list. Hopefully some pattern can be found making the acquisition of the quality models a bit easier.
