This one is possibly a later production board, possibly with a 16K memory mod.
White 6502 and plastic film decoupling caps.
Some pictures show the keyboard connector plugged into the socket for the 6800. This was just a mistake done by someone.
Dag Spicer from CHM and Woz had a look at this Apple-1.
Until November 2019 it was wrongly specified as CPU 6800. It is, as usual, the 6502.


Joe Altieri of San Mateo (California, USA) owned the Apple-1. According to Joe Altieri, he bought it from Steve Jobs late 1975 at a Homebrew Computer Club meeting.
Donated to PBS (public TV) fund-raising auction for a public radio station in Astoria and sold to Janet Keim for US$ 90. Dag Spicer (a computer historian and curator from the CHM) did the authentication of this Apple-1.Maybe it was donated by a member of the Homebrew Computer Club.
Later sold to Ian Lynch Smith for US$ 10,000. An Apple developer ever since. He never changed anything to the Apple-1 board.
On loan to CHM by Ian Lynch Smith.
The Apple-1 was on display at a MacWorld Expo 1998. It was on tour in Europe 2019
Renamed on Oct 31, 2019 from CHM 2 to Joe Altieri, the name of the first known owner.
