The Weird Stuff I Find

I was cleaning up my RPG folder on my computer this week, a never ending process, and stumbled across this text file dating from 1997. It appears to be some sort of classless advancement system for AD&D 2nd edition, but I have no memory of writing it. It also appears to be implementing spell use based on a point system. It looks a bit incomplete too (some of the XP costs near the end are a bit sketchy too). Look familiar to anyone?
