I remember reading an article in a magazine once, it was weird, no wait, wired, about how scientists use it because it is so rugged. I remember one guy that studied something that lived in the ocean, maybe whales, and he wrapped his in saran wrap to water proof it. The only people that use this computer anymore are people that just need very basic data entry and need a computer they can drop it into a volcano and not worry about it breaking.
No wait, I did a google search of the Trs-80 and realized I'm thinking about a Tandy Laptop. Were there any games for the Trs-80? I can't imagine anyone using it for anything other than retro gaming anymore.
