You seem to have forgotten AD&D's psionics. Completely different power structure and resource management.

If you want to include obscure supplements or appendices, then that's when spontaneous spellcasting came around. It was still unified before that point, regardless of whether that point came in 1E or 2E or 3E.You seem to have forgotten AD&D's psionics.

The psionics appendix in the AD&D DMG wasn't exactly obscure, since you needed to use it to run critters like Intellect Devourers, Mind Flayers, and Demons. (Possibly Devils and other extraplanar beings as well- don't recall.
