The recent conversation on low serial numbers reminded me of this photo. It was taken in March of 2010 while the Huston Bros were preparing to sell S/N #1 on eBay. S/N #1 has Shugart mechanism S/N 4 inside I think. I believe Woz has Shugart S/N 1. S/N 2 has Shugart S/N 2 inside.
I bought it before they were available, direct from Zip Chip. It was 8-10 months before I received it... This would have been like a Predecessor to KickStarter, sending money, in Advance, so you can get one of the First Ones...
Here is a picture of my original Apple II Rev. 0 12K system with Datanetics keyboard from 1979 that still works.
(Notice the 4K memory blocks along with unlabeled non-serialized power supply (fresh from out of test at the time.))
