I wrote all of my high school and college reports using the TRS-80 Model I (with expansion interface, 48k of RAM, upper/lowercase modification, single 5-1/4” disk drive, and dot matrix line printer). The ribbon cable between the keyboard and expansion interface was very finicky, and could cause the computer to reboot by just looking at it funny (or so it seemed). I developed the habit of saving my work every two to three minutes.
