I don't know of any 660AV schematics which are available, but those of the 840AV are. Both Macs are very similar and some circuitry appears to be almost identical.
Hello Kai, are your excellent replica boards already available somewhere? I have a Classic with severe battery damage which I’d like to 'reload'! Of course I’d be happy to populate it myself, so I just need the board.
Many thanks!
Robin
