Sure.
OSRIC is my attempt to recapture the 1e systems and algorithms in an open gaming context. The core rules are free in .pdf format.
You can download them here:

Anyone can publish material and say it's OSRIC-compatible. They need not ask my permission or pay any fees or royalties, provided they comply with a set of terms and conditions that I like to think are fairly reasonable -- they're there for my protection and everyone else's.
At the moment, the OSRIC rules are in a kind of open beta phase. (This doesn't matter to publishers; few people play OSRIC as written. They simply use their OSRIC-compatible material with the original 1e rules, which is what I indended.)
I'm hoping to move to a reasonably final version shortly.
To my surprise, there seems to be some demand for a reasonably-priced print version of OSRIC... perhaps peoples' 1e hardbacks are starting to wear out? In any case, I'm working on providing the core rules in print format at cost price (likely to be under $7.50 for the 132-page 8.5"x11" softback).
This thread is just to keep people informed about recent progress I've made.
