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.


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.


White ceramic CPU MCS 6502 Motorola (date code 11/77), plastic PIA Rockwell. 8 KB DRAM. 3 big blue capacitors, 4 golden capacitors. Because it was handed-over as an unpopulated board, it looks like, most chips are from later period.


No ACI. Triad transformers from 1975. Additional power cable added to the mainboard.


Working. The circuit board has been signed by Steve Wozniak.
