(This was before laptops were so prevalent and all we had for monitors were CRTs).
Back when I was in college we had a group assignment for our final project in one of my programming classes. Four of us grouped together. The fifth member of our team, Anna, had to be assigned to a group because nobody wanted her. We were the unlucky group that got her.
One Saturday, the group brought our computers to my buddy's apartment to have a day of programming and project discussions. We had been set up and working for about an hour when Anna arrived. While the rest of us continued to work, Anna carried all her stuff into the apartment and attempted to set her computer back up. After about a half hour (just a guess as I was busy working on my part of the project, but it was a long time), she asks for assistance. I'm the closest to her, so I jump up to help. All she has connected were the two power cables; one into the system and one into the monitor. I look at the connections on the back of the system to see what might be the problem. I don't know what I was expecting to find, but everything looked fine. So I asked her what was up. She said she was having problems figuring out what connections went where: monitor, mouse, keyboard, speakers, zip drive, etc. Shocked, I took a second look at the back of her system and the cables ends.. As I turned to go back to my work I said, "Anna, if you can't read the labels next to the connections, try matching the colored ends to the colors on the ports." EVERY connection port on the system was labeled and color-coded to the cable end that needed to plug into it.
I'm embarrassed to say she graduated with the same degree that I have.
