Description

The circuit board has been signed by Steve Wozniak.
The extra connector has a remarkable background (information is Elmar Baum's son): My father worked on the Apple II power supply with Rod Holt, and the extra connector (and extra diodes) on his board was used to power Apple IIs before that switching supply was completed.


History

From the owner:
This board was from a batch of 25 which were never sold and in a stack of boxes on Steve Jobs’ desk. Steve allowed employees to take them as the company had stopped selling Apple 1s in favor of Apple IIs. Elmer Baum (Apple Employee #34 and financier of the 1st run of Apple 1s) took 2 boards. My father, an engineer in Silicon Valley, was given one of these boards and kept it for many years.
It is up for auction in December 2019 at Bonhams NYC.


Auctioned
