24 tables if you count sub-tables. 8 if you don't.Well, the original rule had a lot more tables for the random dungeons. You rolled as per 5ed but, included were random traps (with a table), random monsters (16 tables if I remember correctly), random room content ( empty, monster, treasure and monsters with treasure). It was not only a set of tables for random directions and rooms. You could litterally build a whole mega dungeons along with furnitures, magical fonts (which had random effects, both good and bad), sliding and shifting rooms and even portals... The 1ed random dungeon generator was a lot more complete than its 5ed counter part.
That is why I think that we could pull DMless play with the 1ed random dungeon generator but mot with the 5ed one. The only drawback would be that ECL of encounters might not always be on spot as it could be possible to have 4th level monsters (or 5th?) as possible encounters. But otherwise it should be feasible.
Edit: If you want a REAL solo-dungeon generator, get the Central Casting: Dungeons book. It's really good for that. Makes the 1e DMG look like child's play.
