At this point you should just have a >20 years ago section on there (I would label it "prior history" myself), and include projects you worked on. That's over 20 years ago. Unless you worked on something you really want to highlight, just fudge them altogether.
I am guessing you don't work in tech in the US though? I was a bit worried about doing a third "three and out" while looking, and 10 years prior in finance, it may have been an issue, when I was looking at tech companies, no one even batted an eyelash. One HR recruiter even quipped that these would be relatively long tenures in the startup world.
Oh man, I know what you mean - it's kind of crazy. When I'm at a company for more then 2 years, recruiters start joking that I'm an old timer and must be dying for a change! I'm all for moving when the time is right, but I like my job and looking for a new one is stressful!
