CP/M powered my first computer, a Kaypro, forty years ago. Got my master’s degree with it. WordStar was a wonderful program. I still remember the keyboard commands.
Built my first PC out of floor sweepings in 1982. It was a Z80 machine.
Still have it stored.
I even had a flight simulator for it. Keyboard control, not joy stick.
Forgot to tell you the OS, it ran NewDOS80.
I later bought a Kaypro 2000+ clamshell "laptop" in 1988.
I used my Kaypro PC until it died in 1993. I continued using WordStar for DOS until the late 2000s, when I switched from XP to Win 7, which no longer recognized an external 3.5 drive with my WordStar discs, or my parallel port printer which WS insisted upon. I was unable to get WS to recognize my USB printer, so I had to switch to Open Office Writer.
I had bought WordStar for Windows in the 1990s, but I never used it.
First computer I personally owned was an IMSAI 8080. You could program the thing with a version on CP/M or use the front panel. Also had a Kpro, TRS 80 and generic 8080 and 8086 computers.
