Description

This was a never-populated/unsold unit taken from the stack by Adam Schoolsky, who was an Apple employee at the time.
4062 label on front. 49 sticker on back. Round stamp with number 6 next to the heatsink.
Number “4” is handwritten on Texas Instruments low-profile sockets 3 and 4.


History

Purchased from Adam Schoolsky by LCF group (David Larsen) in 1994.
David Larsen wrote, "I purchased it from Adam Schoolsky — he told me he was the second employee of Apple. This could be true, as Woz mentions him in his book *Woz* — the computer was given to him by Woz, and when I purchased it, I really got a lot of additional neat Apple artifacts. The computer has never had chips in it and is just like new, most likely the only one like it — I mean never loaded with chips. I have letters and lots of other documents from Adam as well."
Auctioned at Charitybuzz in 2017 for \$401,000. This includes 3 original issues of *Silicon Gulch Gazette*, the First West Coast Computer Faire Conference Program, and the "Zaltair" brochure.
