Found this video from youtube. Pretty hilarious =D
"This is gameplay footage from the original game "Starcraft" as it was released in 1984. My uncle worked as an assistant programmer for Blizzard/Activision in the early 80's. I found this in his closet next to an old Colecovision."
Unfortunately there was one geocites website that contained a detailed report on the changes with many pictures from alpha to beta, its dead now though T__T.
Obvious fake, which I would've found amusing had the author of the video not bullshitted about his "uncle" working for Blizzard back in the 80's when Blizzard didn't even exist until 1991 (under Silicon and Synapse). Instead I was just annoyed.
