Well, there's a free public domain release clone of this "FASERIP" system called the 4C System. You can download it here.
You can also find the forum 4C4Ever! (dedicated to the 4C System) here.
This is great for the indy publishers interested in providing new material for this classic game. In fact, once the Labyrinth Lord adventures I have planned are finally finished, Prime Requisite Games might set its sights on publishing some 4C material. We'll have to see what the future holds.
Here's to much success to 4C.
