My college crew's longest 1e campaign ran from Fall 1993 to Spring 1995. This was after 2nd edition was well under way, but our DM wanted to use 1st edition, so that's what we used, happily. We had weekly 6-8 hour sessions, mostly pretty classic dungeon crawling (smash doors, get loot, retreat to town).
I want to say we used RAW, but it's actually hard to remember! Certainly I remember we kept a copy of the DMG open to page 75-76 for the combat tables, rather than using THAC0, but we used 1d6+Dex bonus for initiative. We didn't use the weapon vs AC type modifiers, and didn't count segments for spellcasting. We did consistently use miniatures (however improvised), and marching order was pretty important. Gold got counted towards XP. We paid training costs. Healing without spells took ages. I think it's notable that (other than arguably initiative) our DM didn't add any house rules-- they just skipped a bunch of the book rules.
If we had any rule disputes, I don't remember them now. I do remember the time our characters splurged at the tavern and we the players roleplayed getting progressively drunker for 90 solid minutes, falling off our chairs laughing. And I remember the time our DM and the elf F/M-U/T both forgot that elves are immune to ghoul paralysis, which contributed to a TPK that we had to retcon.
We switched to playing Vampire: The Masquerade for the rest of college, but later came back for D&D 3.0, then 3.5, then 4th...
And just this year our group had our first face-to-face game in ages using D&D 5e/2024. At our next game I'll have to ask our DM if they recall how closely they hewed to the book back in the day...
