    RTC chip replacement

    Hi everybody I‘m looking for a replacement of my SE/30‘s battery-bombed RTC chip. I know of the ATTiny85 source code, but my machine is not accepting it and refuses to boot from Floppy or HD. Has anybody experience with this replacement chip or does somebody have spares? Many thanks, Robin

    Centris / Quadra 660AV schematics

    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.

    Logic Board - Macintosh Classic Reloaded

    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
