Anyone has schematics for 270c and 520?
Posted by: croissantking on 2026-06-20 09:18:24 Looks like they've been released: Macintosh PowerBook Duo Prototype Schematics Schematics of a 16MHz EVT motherboard codenamed Metropolis, a prototype from early PowerBook Duo development. Since it features a 68030 processor it's likely that these are very close to production Duo 210/230/250/270 models -- but be careful... tinkerdifferent.com
