I wrote my first computer program in 1978. I cut my teeth on the Chicago Public Schools mainframe, a Trash-80 and an Apple II.
My friend and I were doing memory upgrades on 8088 machines before you were supposed to be able to do them.
I built all the computers in our house. I have a fairly good word-of-mouth thing going fixing jacked-up Windows machines (and promoting Linux as a way to avoid further problems, but who listens?)
But God forbid I should tell the 15 year old that his computer is running slow as dirt because the servers on his silly online RPG are overloaded....
