For me old school is more about style of play and themes than calendar dates. While THAC0 was a big part of old school, I look at it more as Gygaxian player challenges and dungeon crawls. Solve this puzzle or find your way out of a maze that I've only been describing that also contains one way teleportation that is so seamless that not only do you not know you were teleported, nobody else in the party notices either. Throw in various tricks, traps and obstacles not only designed to challenge, but to outright kill off hapless PCs left and right. You brought a lot of hirelings as fodder, right?
There's nothing wrong with that style of course if it's what your into. But that also means it can be somewhat edition independent, although complaints about there being relatively few "oops you're dead" mechanics and PCs actually having a decent chance to survive come up when discussing the current edition.
