Wozniak couldn't do what Allen did, as Wozniak didn't have access to a PDP-10 mainframe (as it was known as, back then), or any other larger computer. He bought a 6502 CPU at the Wescon Trade Fair in 1975, because it was so cheap ($25, a fraction of the cost of alternative CPUs). It was so cheap that he could afford it. He wasn't sitting of a lot of family money like Gates either. In any case, if Wozniak did have a PDP-10 sitting around then he would surely also have used that one for some purpose.
