One of the things I always found interesting was that the Moldvay Basic and Cook Expert books were 3-hole punched. The idea was to cut up your rule books and then re-assemble them in a binder.
While I liked this idea and thought I would do it once the Companion rules came out, I never could bring myself to cut up my rulebooks.
Now with the Basic and Expert books out on PDF I might print them up and do this.
Did anyone do this back in the day? How did it work out for you?
