There are currently 3 Apple II's (not on eBay but 2 of them have me a bit suspicious...
That one is from Russia and is VERY clean - but there is no serial number sticker on the bottom case, and the photos don't show the motherboard date. I can't quite tell if its a Rev 3 motherboard or not.
To me, the keys on the keyboard look to be of the later type (more rounded/sculpted) and no information about the motherboard revision, or motherboard dates. Might be totally legit, but I would have to have a lot more info before I would even consider bidding on this one.
Weird how these seem to pop up in groups on eBay. There are 3 or 4 Apple II's on there now, and a ton of II+ and IIe's!!
