It would probably be “1000s”.

Smaller roman numerals before larger are subtracted from the nearest larger numeral.

So, IX (1 10) is (10-1)=9. “LLM” would be (50 50 1000) which would probably be (1000-(50-50))=1000. It could be (1000-(50+50))=900 but that would more correctly be written “CM.”

Who used those triangular pastel buttons? I remember seeing them on some friends’ computers but not on any Dells or Gateway 2000 machines. Maybe Compaq? Or Packard Bell?

I saw Slackware running on a similar config, although it was probably a 486/50 or 486/66.

I remember my dad’s friend upgrading our PC clone to 640K. He used a soldering iron.
