Some power supply components are missing - Woz might have used this board for voltage margining (conjecture). The switch board has no wires at all. White 6502, disk capacitors and rare white 4096 DRAM chips.
This one is said to be on loan to the Computer History Museum from WOZ's personal collection but that is not true. The acquisition record available online shows it was actually donated by the Dysan Corporation.
