The second public draft of the rules and spell list for Microlite 74 is available on the message board. A few minor rules changes have been made to give the system more of that 1974 first Fantasy RPG flavor and feel and I've started to make the spell effects more closely resemble those of that era. Sleep is as powerful as it used to be, for example.
Microlite74 is based on Microlite20. Randall's also including info on Judge's Guild products over at the RetroRoleplaying site:
I've added a number of Judges Guild products (mainly adventures) to the Original Dungeons & Dragons section of this website. Although there are more to come (like the Wilderlands of High Fantasy), I think this is a good start.
