Handwritten Serial Number on the Back

Not every Apple-1 computer has a serial number! Some (but not all) Apple-1 units from the 1st batch have a handwritten number on the back, which is clearly a serial number. None of the 2nd batch units received a serial number. In 2022, a forensic analysis led to a minor sensation: the serial numbers on the Apple-1 were written by Steve Jobs. More information about it.
