Description

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 made by someone.
Dag Spicer from CHM and Wozniak had a look at this Apple-1.
Until November 2019, it was wrongly specified as having a 6800 CPU. It is, as usual, the 6502.

History

Joe Altieri of San Mateo (California, USA) owned the Apple-1. According to Joe Altieri, he bought it from Steve Jobs in late 1975 at a Homebrew Computer Club meeting.
Donated to a PBS (public TV) fundraising 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) authenticated this Apple-1. It may have been 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 on the Apple-1 board.
On loan to CHM by Ian Lynch Smith.
The Apple-1 was on display at MacWorld Expo 1998 and was on tour in Europe in 2019.
Renamed on Oct 31, 2019 from CHM 2 to Joe Altieri, the name of the first known owner.
