Originally called Exec-8, named after the Univac 1108. Renamed OS/1100 
when the 1108 was replaced by the Unisys 1100 series (1100/40, 1100/60, 
1100/80, etc. I don't know what year that was, but you are probably 
right that it was a latecomer. Renamed OS/2200 when the 1100 series 
became the 2200 series.
