From the man himself:
I'm happy to announce that version 1.0 of the Microlite20 OSS and the Advanced Microlite20 OSS roleplaying games are finished and available for free download. "OSS" stands for "Old School Style". Where Microlite74 and Microlite75 attempt to recreate old school games from the Microlite20 rules, the Microlite20 OSS games were written to encourage the "old school style" play using the much more standard 3.x edition base Microlite20 was written for. Microlite20 OSS is a Microlite20 variant designed for old school style play with a modern game system and nearly any 3.5 fantasy adventure module or setting you can pull off your shelf.
