For all you generations Xers and Y'ers, here's my personal history of computers.
In the eighties some computers used tape drives to load files because hard drives were too expensive. You really needed some patience for the tape to load because it took forever! Trust me, this was a painful experience.
And then floppies were the rage. My first Mac SE was really awesome because it had TWO floppies..one was used to load the operating system, the other was used for applications and files. This meant you didn't have to continually swap floppies whenever the operating system needed some data. So awesome!
At that point we were making the transition to 2400 baud modems, which was really great compared to the 1200 baud modems. Some 9600 baud modems were available but they were hard to get to work and gave a lot of errors. Plus they were sooo expensive...around $1000.
And then in the early 90's my Mac IIsi was really fast...I bought a 60 megabyte external drive for $600. And backing it up was simple - just buy a case of 50 floppies and label and swap them in and out when the backup program finished each disk and ejected it.
To be continued...
