They are playing ZORK!  On Big Bang Theory!  ZORK was the first real video game I ever played.  Dale was working on the pipeline and we were living in a 25 foot trailer in Blythe.  One of the guys had an old TRS 80 – the kind that was all one piece, monitor, keyboard, and all.  He let me use it and I filled a legal pad with notes as I worked my way through the text based adventure.  I LOVED it!  You typed in north, south, east, or west and went that direction.  It would sya something like “You are standing before a wooden door” and you would type in open the door.  There were objects to find and many of them were needed to get to othe parts of the underground empire.  You can only carry so many items at a time so you have to figure out what to carry and what to drop.  There are some “bad guys” and some dead ends so it helps to draw a map as you go along.  In this very first version of ZORK, ZORK I there are no pictures – only text.  Your imagination provides the pictures!

This is my favorite show EVER!

P.S. If you are curious there is a java version of the game that you can play online ZORK

Have fun 🙂
