Ebay Listing 322853882595 (alternate source)
Described as a Commodore C65 for sale in the listing as:
This particular unit has serial number 16. It is in absolute top physical shape (no yellowing of plastic whatsoever) and is fully working. It has a RAM-Expansion (C1990/COMMODORE AWK 313384/C65 RAM EXPANDER ASSY 313381) So in consequence the only numbers which matter are the boards revision and maybe the sticker on the EPROM. The motherboard, is a revision 2B. The sticker label on the EPROM looks genuine and states "390488-03".
