Again, not accurate. The MM came out in 1977. The PHB came out in 1978. The DMG came out in 1979. There were not rules to play characters by until the PHB in 1978. By the time the DMG came out in 1979 people had already been playing for a year. Most groups simply stuck with the rules from the PHB, regardless of what later books added. So yes, it was just roll 1d6. Because that's what's in the PHB.
This, again, is just incorrect and ignores the multiple exceptions in the PHB, from spellcasting to psionics to dexterity adjustments (if you are wearing light gear) and so on.
But sure, if you want to ignore the rest of the rules in the PHB, and say that no one read the DMG in 1e (hey now!) ... okay? Not sure why this is the hill you are choosing to die on, but I like a good AD&D discussion.
