When I graduated HS i actually typed 95 words a minute on a manual typewriter. That is how prepared we were to go out in the real world. A roll of film was a roll of film and 35 ml cameras still use them, instamatics were a drop in cartridge. The first tape recorders also had film that were threaded through on two wheels that turned and not tape cartridges.
Why are you trying to make us feel old?
