Several years ago, I began writing an assembly language reference manual for PDP-11 computers that was modeled after notes from a VAX assembly language class that I took. A few minutes ago, I discovered it amongst other files in my PDP-11 files archive and an idea crossed my mind: it's not doing anyone any good just sitting there on one of my systems' hard drives, so, if anyone's interested in it, or interested in completing it, let me know.
