I suppose I'll be sorry for this, but I want to mention that one of the hardest to find early 6502 systems just showed up on eBay: the PAiA 8700. But it wasn't on the vintage list; it was on the music instrument category. Most of these were built into keyboards. I've been looking for one of these for 5 years and only seen 3 of tem on eBay. Always get outbid. Had to stop bidding on this one at $93.. Anyway, if anyone else wants one for their collection, take a look at this: 110079964730 You can see the keyboard and the display in one picture. The description gives it away. So if you are looking for these, do a search pointed to midi keyboards or PAiA. Billy
