The info is all essentially designed around the Basic/Experienced version of D&D from back in the late 70s-early 80s, but those will convert pretty easily to most Old School Rule role-playing game systems, and many may simply find it useful for the maps and ideas alone. It generates a VAST amount of information besides a nice little hexmap - including dungeon plans - along with contents, settlements, factions, nations, etc.
A colleague on one of my Discords pointed me towards the Hexroll random hex-map generator this evening.
