'''Expensive Typewriter''' was a pioneering [[text editor]] program that ran on the [[Digital Equipment Corporation|DEC]] [[PDP-1]] computer,<ref>[http://archive.computerhistory.org/resources/text/DEC/pdp-1/DEC.pdp_1.1972.102650079.pdf "Expensive Typewriter" (manual)] {{Webarchive|url=https://web.archive.org/web/20160304120542/http://archive.computerhistory.org/resources/text/DEC/pdp-1/DEC.pdp_1.1972.102650079.pdf |date=2016-03-04 }}, August 1, 1972, MIT</ref> which had been delivered to [[MIT]] in the early 1960s.

==Description==
Since the program could drive an [[IBM Selectric typewriter]] (a [[letter-quality printer]]), it may be considered the first [[word processing]] software.  It was written and improved between 1961 and 1962 by Steve Piner and [[L. Peter Deutsch]]. In the spirit of an earlier editor program, named "[[Colossal Typewriter]]", it was called "Expensive Typewriter" because at that time the PDP-1 cost a lot of money (approximately {{Currency|100000|USD}}) as compared to a conventional manual typewriter.<ref>{{Cite web|language=en|url=https://www.computerhistory.org/pdp-1/ad6b7367b8cbd0133326c23c49a029d0/ |title=PDP-1 Price List|website=www.computerhistory.org|access-date=June 17, 2022}}</ref>
