Serial number on the back

The serial number on the back of the Apple-1 was most likely written by Steve Jobs. According to available information, a forensic analysis has not yet been performed for this Apple-1. However, for some other Apple-1s with a serial number on the back it has been confirmed that it is Steve Jobs' handwriting. More information.

On March 2nd 2018 Curator Cate Mills wrote to us (thanks for the update):
Information Purchased from Winston Gayler by Computer History Association of California (now defunct). This occurred due to a donation by Larry Tesler (at one time, chief scientist of Apple) in late 1993 or early 1994. Displayed at FRYs in the late 90s" is likely correct.
The CHAC materials were donated to the Perham Foundation BEFORE all of this collection came to History San Jose in 2003. The Perham Foundation no longer exists, and the remains of that collection are with several different museums, including ours and the Computer History Museum.
Powered up and operated in May 2013 in a documented news story (San Jose Mercury). Woz and a number of other people and Apple 1s were present.
