I owned a computer in the ‘80s and ran autocad and lotus 1-2-3. I had to install a math co predecessor for autocad. I think the CPU was an 80386.

You probably remember VisiCalc and Wordstar. Lotus wiped out VisiCalc and Wordstar couldn’t compete with Microsoft Word.
Wordstar couldn't make the transition from CP/M to DOS. They did port it to DOS, as I recall, but it never caught on. But it was Wordperfect, not Word, that killed Wordstar. Wordperfect lost out to the Microsoft empire in the DOS/Windows transition, but it was very popular in the gap between Wordstar and Word when DOS ruled the world.
I still remember some of the Wordstar dot codes. That's wasted space in my brain.
