Sure, you could "hit Armor Class 0" in 1st edition AD&D, and there was a number you needed to roll on a d20 to do so, and in that sense I suppose it existed. But as you say there was no reference to THAC0 per se until 2nd edition. :?: In any case, I was just razzing the original poster :). I was still playing 1e in the '90s, but I'm pretty sure our group did use THAC0 at that point, along with a few other "imports" from 2e.
Zenopus wrote:THAC0 definitely started appearing in 1E modules at some point. I just randomly opened up a handy module (UK4, 1984), and it's got THAC0 in the monster stats. So, now the question is - what's the earliest appearance of the term?
