Teaser quote:
"If I think about one thing that really captures that era, is that it was exciting. It was exciting, it was fun, it was something new, it was something you could share - you could join a user group, there were all these magazines. ... A lot of information out there, a lot of stuff to learn, a lot of stuff to have fun with and share."
