History

Information as of May 2023 from the current owner: "I actually had one other Apple 1 that was given to me by Steve Wozniak many years ago (1979). My wife and I were out to dinner with Woz when our house in Oakhurst, CA, burned down, destroying my Apple 1. Woz heard about the fire and contacted various friends to see if anyone wanted to sell their Apple 1. Two people contacted me, but I have zero recollection of who they were. One person I paid, and the other I swapped some software with." The owner wishes to remain anonymous. Therefore, the two Apple-1 units are temporarily named Ken 1 and Ken 2.


Components

CPU from 1979 (not original), PIA AMI S6820 (7601), 4K Mostek and 4k Signetics DRAM (not original).


Equipment

All mounted on a wooden panel in a plexiglass case.


State

Very good overall condition. The CPU, all N8T97s, all DRAM, and at least one 7400 and one 74166 are not original. A small piece of the board was cut out at the bottom edge between areas 2 and 3.
