If you are old enough to have played Wolfenstein 3D, when it was new.... sigh in :)
If you are heading for google to find out what that is, you are not old enough :)
If your first computer had Windows 95 or later on it, you are not old enough :)
If your first hard drive was bigger than 100mb, you are not old enough :)
If your first use of the word "gig" had nothing to do with music, photography, fish or frogs, then you are not old enough :)
If you got your first calculator any earlier than High School, you are probably not old enough :)
If you have actually stored data on all three of these, then you might be old enough...
I am curious how many of us old codgers there are out there in the Minecraft world.
