So after some negotiation I picked up this Apple II Rev 02:
He was asking a way out $3000 for it at the beginning (actually $3900 with a J2+ he was selling with it). I could not find a Rev 02 sale on Ebay recently and thus had nothing to go by, but I figured I'd offer $1100 based on parts value and a few hundred in loss if it's not recoverable (he accepted). I've never seen a Rev 02 on ebay (not that I look every day). Interestingly, this unit is only 27 serial numbers earlier than this Rev 03 that just sold:
Issues: doesn't power up properly, has visible rust on a few chip legs, keyboard isn't working. Also Applesoft rather than Integer ROMs (I have three sets of Integer ROMs of correct vintage so I'll just swap those). He made an effort to swap ROMs to see if he could get it to post properly but ended up breaking off a chip leg (which he successfully removed from the socket). I've done battle with recalcitrant Apple II keyboards before so I'm not worried there, and like I said, if the motherboard is trash, I'm happy to keep it as a static example of a Rev 02 along with the other revisions of the board I already have, and maybe sell the rest and recoup a few hundred back that way.
What do you guys think? Interesting that it has Japanese characters silkscreened on the front of the keys. And I wonder what it tells us about when Apple changed from Rev 02 to 03, if anything. Or if it was using certain Revs overseas and others at home. Pretty sure I've seen a few Rev 03s that were earlier than this one.
If I do get it back to working, original spec, what would be a fair asking price for it? Also -- being of use in Japan at some point, does that mean it has different character ROM, or something else? Did these actually output Japanese characters?
