List of all original Apple-1.
If you are a first time visitor and not familiar with iconic Apple-1 computers, please read all the information first.
Go to previous entry #23 - Go to next entry #25
Note: This is the 24th entry in the list and not the 24th Apple-1 produced. The Apple-1 does not have a regular serial number. Only some Apple-1 got a handwritten serial number.
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.

Restoring the Apple-1
Mounted on a wooden board. A mix of DRAM. All modifications were done by the first owner. A metal strip is glued on both PROMs as a heat sink. This work was also done by the first owner.
On March 2nd, 2018, Curator Cate Mills wrote to us (thanks for the update):
Information: Purchased from Winston Gayler by the 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 Fry’s in the late '90s" is likely correct.
The CHAC materials were donated to the Perham Foundation BEFORE the entire 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.
