From the introduction: This began as an attempt to "fix" the AD&D system to make it playable. ... I set out making changes in the system with a few goals in mind: First, I felt that the current magic system had too much of a tendency for low level spellcasters to be "johnny one shots" Second, I detested the weapons and armor restrictions Lastly, I didn't like the hit point system User summary: The document presents a rather fragmented suite of rules to "fix" perceived shortcomings in the base game. The document probably was created abt. 1990 though the archive date is used, here.
