O26, a full screen editor, was named after the IBM model 026 keypunch
(the first character being an alphabetic "O" rather than numeric "0" due to operating system restrictions).
The editor could be run on the CDC 6000 series
, and later Cyber-70 and -170 series
operator consoles. According to source code listings of the SCOPE
version of O26, it was written in 1967 by CDC programmers Greg Mansfield and David Cahlander.

Time-sharing
Time-sharing is the sharing of a computing resource among many users by means of multiprogramming and multi-tasking. Its introduction in the 1960s, and emergence as the prominent model of computing in the 1970s, represents a major technological shift in the history of computing.By allowing a large...
