The Apple-1 Registry

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.

Description

Wooden case with built-in transformer and keyboard.

History

The original owner, who had brought the computer in to the meeting in an effort to sell or trade it, met with the current owner who expressed an interest in it, and a swap was made. At the time, the computer was in completely functional condition.
Eventually he contemplated adding diskdrives to it. Being a technician for a large disk drive manufacturer at the time, he arranged avisit to Apple Computer's headquarters in Cupertino, California, to discuss the possibility ofadding disk drives to the computer. The conclusion was that a disk drive could be added, but not without a significant amount of work that owner was not interested in engaging in, so it was at that time that the computer was finally retired. The Apple Computer visitor badge, visible inthe photos of the interior of the enclosure (with the owner's name blurred out to protect hisprivacy) was put there as a memento of this visit.
Bought in 1981 at an Apple users group meeting in Santa Clara, California, USA.
An interesting red label from Apple Computer Inc is inside with the name of the owner and date 8/26/81.It is from a visit of the owner at Apple's headquarter in Cupertino. He discussed the possibilities to add a disk drive and kept the visitor badge.
Maybe it was sold at the VCF 2003.
