Yep - The Commodore 64 launched a lot of careers for programmers.

After college, the first desktop machine I programmed was the Commodore PET. It looked like it would be right at home sitting on Darth Vader's desk. (Star Wars and the PET both came out in 1977)

It had integrated monitor and cassette storage :) My employer purchased it to control scientific instrumentation via the PET's IEEE-488 interface. It was very odd for Commodore to integrate that interface in a personal PC as it was only used to control industrial / scientific instrumentation, although IEEE-488 hard drives arrived in the late 70's.
