Oh man, so many memories... I still remember my first interaction with a bubble jet printer. Back in the day, the electronic card catalog machines at Ball State University's library were hooked up to these early bubble jet printers. I remember what was distinct about them was that they held on to all of the old dot matrix conventions: the head was mounted horizontally and in front of the roller, and the paper was still fed by sprocket wheels. The speed was pretty decent too!

One that I would have liked to see under the hardware section is thermal paper fax machines. I still remember working in my parents office as the "gopher" when I was in grade school. One of my jobs was to make photocopies of all the faxes so that they could still be read after the thermal paper faded.

...good times...
