Univac Text Editor

ED or ED-1100 is an interactive text editor implemented on the UNIVAC 1100/2200 series.

"'ED was developed at Univac in the mid-60s. It was loosely based on the Project MAC editor developed for the MULTICS system at MIT.'-Tom McCarthy"

"'Project MAC editor was programmed by Jerry Saltzer as a way to produce documentation. In fact, that editor became the first interactive word-processor ever programmed.'"

"'The command TYPSET is used to create and edit 12-bit BCD line-marked files'"

ED was improved by Dr. Roger M. Firestone in the mid-1970s.
