History

Mitch Waite told Mike Willegal:"I bought mine from a Byte Shop in San Rafael after seeing Jobs demo it at the Homebrew Computer Club. I built a weather station on my houseboat and got Steve Jobs to drive to Greenbrae to see it in action. I wanted to write a computer graphics book and use it but he told me they had a much better Apple II coming out and I should come to Cupertino and he'd give me one. There is an amazing story that visit and subsequent relationship - you can read it at my ancient blog mitchwaite.com (click books). Woz modified the PIA on the board so I could control a homemade wind speed device on the roof with assembly language and the sweet 16 Assembler."
In 2019 Mitch told Achim Baqué "I bought it at the Marin Byte shop, under the clock tower, on Francisco Blvd in San Rafael" .
Apple-1 computer was renamed from "Mitchell Waite" to "Weather Station" on request of the Mitchell Waite himself. Usually the name of the first owner is used, but he is the first owner and should have the choice.

Mitch wrote in 2019: Mitch used his A1 to display weather information gathered from the roof of his houseboat: tide height, wind speed, temperature. More details will be released in 2020.

It was on exhibition at Vintage Computer Festival West 2019 at the Computer History Museum in Mountain View. Achim Baqué verified it and made pictures. Owner is known to Apple-1 Registry curator Achim Baqué.
