Expensive Typewriter
Expensive Typewriter was a text editing program that ran on the DEC PDP-1 computer[1] that had been recently delivered at MIT.
Information
Since it could drive an IBM Selectric typewriter (a letter-quality printer), it may be considered the first word processing program. It was written and improved between 1961 and 1962 by Steve Piner and L. Peter Deutsch. In the spirit of an earlier editor, named "Colossal Typewriter", it was called "Expensive Typewriter" because at the time the PDP-1 cost a lot of money (approximately US$100,000) as compared to a typewriter.
gollark: K is maths. Statistics is maths. QED.
gollark: The p-value is the probability of the thing happening randomly *assuming your null hypothesis*. It is not 1 - the probability of you being right, or something like that.
gollark: This is definitely how p-values work.
gollark: If you use lots of speakers and very good controls you can use a phased array to direct sound at you specifically.
gollark: And telling everyone else to lie similarly.
