PB Duo schematics?

[ScutBoy]

Does anyone have a source for schematics for the Duos - specifically the 270/280 series?

I've found the service manuals, etc. but not schematics.

Not sure they exist.

They are all in a massive vault behind Cook’s desk at Apple.

LOL or maybe their internal archives somewhere.

TO the extent that this is something Apple kept and didn't see the need to destroy instead of archive, it would be at Stanford University. In 1997, Jobs, upon returning to Apple, ordered the archives to be removed and the contents were generally sent to Stanford.

So, I don't know if you'll actually find any schematics here but if they exist this is one of the more probable places.

That would make sense. He canned every product line and spare part for prior machines. I'm going to peruse those...

Well, I emailed the curator with an inquiry as to any schematics or technical documents. We will see.

Let us know what you find! I would have loved to have the schematic when fixing the BSOD (blank screen of death) issue on my 280c. Maybe you'll turn up something that reveals more about the express modem board too. They really decreased the detail level there between the PB 1xx Developer Notes and what was published for the Duo :'(

I did a quick on-line search there and didn't find anything. Perhaps @LaPorta will have more luck with his direct query.

So far what I heard back from the curator was that the vast, vast majority of what they have is there in physical storage and not scanned. I am awaiting to hear how one accesses the main documents in person, but with COVID it appears the campus will be closed for a long time with no chance of looking things up. However, the possibility exists for one of our CA friends here to be able to peruse them someday and perhaps obtain schematics for everyone.

Cost would be insane, but if they ever set it up for research like the National Archives, that would be wonderful. Might the Woz be contacted to fund such an endeavor? It would be very sad to see so much technical history molder away in storage un-scanned.
