What do you guys make of this? Auction says it is a "very rare" (haha) blue 6.2B motherboard. Think it's C= original or did someone just replace it with whatever they had on hand, due to battery damage or somesuch?
Likely a repair job, you wouldn't find a oddball color slot on a late production board like this, maybe you would on a older prototype or very early board.
those sockets were available in blue,green red,depending on the mfg.
