Jobs and Woz, as surprising as it might sound given the difference in personalities, were friends, based on what I've read, which is Woz's interview in Founders at Work and Sculley's Odyssey: Pepsi To Apple.
A lot had also changed by that point - namely they failed in selling the technology to Excite. Would they have stayed friends had they gotten the $1 million they wanted?
Shared trials make and break friendships.
They may not have been friends when they started collaborating on their first research project, but at the moment they were "co-founders", they had already become friends.
