ORVYL is a time-sharing monitor developed by Stanford University for IBM System/360 and System/370 computers in 1967–68.[1] ORVYL was one of the first time-sharing systems to be made available for IBM computers. Wylbur is a text editor and word processor program designed to work either without ORVYL, or in conjunction with ORVYL.[2][3]
