Not to be over picky, but from my first memories of the Internet at uni (1990) there were 5 tlds, in addion to the ones you mentioned were ac (academic) and gov. Both are not open to the general public though so your point stands.

Wasn’t it .edu for education? .ac is the ccTLD of the Ascension Island.
.mil was there from the beginning IIRC. And .int came not much later.
Maybe thinking of ac.uk and such? https://en.wikipedia.org/wiki/.ac_(second-level_domain)
You can easily look this up: https://en.wikipedia.org/wiki/Generic_top-level_domain
