MSTwo

We are in the middle of a scientific discussion, and out of nowhere, a reference to an old and well-known operating system popped up. Our benjamin chimes in, grinning: “MSTwo!”

“MSwhat?” It took a second or two, and then it clicked. She's spanish, you know: “uno, DOS, tres, cuatro,...” And young enough to have never seen MSDOS herself.

Which makes me a relic because I've not only seen it but prepared my master thesis with it. 😑
