Wow, what an amazing story. She gave it to you!? That’s awesome. Congratulations. Hard to believe there are people that generous still in a world where it’s common see a broken, cracked and yellowed Macintosh Classic listed for $500 and “SUPER RARE STEVE JOBS L@@K!” in the title on eBay.
This is beyond incredible, this redefines what a "lucky find" means!
Can you please take a photo of the analog board if you remove it, it would be interesting to compare it to the production one?
Which Apple director owned it originally?
