A 1976 letter has emerged, describing Steve Jobs as a “joker” and his partnership with Steve Wozniak as “flakey”, Bloomberg reports. Written by Mike Rose, who at the time ran an advertising agency in Los Altos, it also reveals that Steve Jobs “wouldn’t trust him”.

Leslie Berlin, an author, stated just how interesting this letter is:

“The note is wonderful in part because it reveals how much Silicon Valley has changed in 35 years,” wrote author Leslie Berlin. “In 1976, two guys trying to launch a tech company from a garage in the heart of Silicon Valley were flakes. Today, someone in Rose’s position might well ask for a piece of the action — payment in the form of a small bit of stock, perhaps?”

Jobs did not end up working with Rose (it’s easy to see why!), and the Apple I manual was produced by a typesetter instead.
