Operating Systems
When the S/360-67 was announced in August 1965, IBM also announced TSS/360, a time-sharing operating system project that was canceled in 1971 (having also been canceled in 1968, but reprieved in 1969).
IBM's failure to deliver TSS/360 as promised opened the door for others to develop operating systems that would use the unique features of the S/360-67:
- MTS, the Michigan Terminal System, was the time-sharing operating system developed at the University of Michigan and first used on the Model 67 in January 1967. Virtual memory support was added to MTS in October 1967. Multi-processor support for a duplex S/360-67 was added in October 1968.
- CP/CMS was the first virtual machine operating system. Developed at IBM's Cambridge Scientific Center (CSC) near MIT. CP/CMS was essentially an unsupported research system, built away from IBM's mainstream product organizations, with active involvement of outside researchers. Over time it evolved into a fully supported IBM operating system (VM/370 and today's z/VM).
- VP/CSS was developed by National CSS to provide commercial time-sharing services. It was based upon CP/CMS.

Famous quotes containing the words operating and/or systems:
“I love meetings with suits. I live for meetings with suits. I love them because I know they had a really boring week and I walk in there with my orange velvet leggings and drop popcorn in my cleavage and then fish it out and eat it. I like that. I know I’m entertaining them and I know that they know. Obviously, the best meetings are with suits that are intelligent, because then things are operating on a whole other level.”
—Madonna [Madonna Louise Ciccione] (b. 1959)
“The skylines lit up at dead of night, the air- conditioning systems cooling empty hotels in the desert and artificial light in the middle of the day all have something both demented and admirable about them. The mindless luxury of a rich civilization, and yet of a civilization perhaps as scared to see the lights go out as was the hunter in his primitive night.”
—Jean Baudrillard (b. 1929)
