You may be amused to read an account of virtual worlds and computer gaming circa 1962 to 1972. You needed imagination to play then! As you needed imagination for the MUDs and MOOs of the early 1980s.
This is an on-line version of an article in Rolling Stone magazine of 7th December 1972 entitled SPACEWAR – Fanatic Life and Symbolic Death Among the Computer Bums. It starts:
Ready or not, computers are coming to the people.
I was using that very same DEC PDP-10 computer at Stanford University via a terminal at Hope Park Square in Edinburgh through our own PDP-10 on the ARPANet just after this period.
Stick with the article to further down and you will get a fascinating insight into some of the folks involved in early creative uses of computers when ARPAnet had less than 20 nodes on it… and people were even then concered about “central computers” and “big brother”.
