The OSRIC Player's Guide, by Seattle Hill Games, has most of the core rules to play the advanced first edition of the world's most popular role-playing game. It is an easy introduction on how to play the game as Gary played it. Once you have mastered the rules herein, you should be able to easily assimilate the full rules from the golden age of fantasy adventure gaming.
Please note; this is not the full ruleset. You will also need a manual of monsters and a game master's guide, which are available online. Alternatively, you can pick up the full OSRIC rulebook from Black Blade Publishing.
