More evidence I was a nerd growing up.  This is my old Advanced Dungeons & Dragons Dungeon Master's Guide.  I don't remember when I got this but it was in the early 80's.  This thing got a lot of use especially in college.  Today you can just sit down and fire up a game and all the stuff is done for you.  Back then if you wanted to have a good adventure you better have a calculator and lots of scrap paper.  Oh and dice.  Couldn't play D&D without the dice.  If you notice in the pics some of the pages still have the paperclip bookmarks on them.  Things like experience tables, loot drops, monster sub-tables, etc.
