There were no blank boards. That's the key. The sockets were wave soldered by the PCB manufacturer according to Woz. There were 2 runs of 100 boards each.
This is also an early layout board (Non NTI) but with different wave soldered sockets than the two known production runs which both used TI sockets even though they were from a different PCB house. This board is from the 1st PCB house that made the "byte shop" boards but has the more expensive and reliable RN sockets. Which implies it predates the Byte Shop boards because of all the evidence.
