In addition to the blog where this post is taken from https://devblogs.microsoft.com/oldnewthing/, you could check https://folklore.org/ for early Apple anecdotes. And also https://www.jwz.org/blog/ for early Netscape/Mozilla stories
I also like https://computer.rip/ - not personal anecdotes from people who were there, but definitely well researched and interesting technology history.
Apparently jwz doesn't like HN, if you click that link you just get an image of a testicle in an eggcup
