The following is taken from a longer note that Garance Dorsehn posted to Tom Valerio's MTS Wiki in April 2005:

At one meeting of SHARE (a conference for IBM users), Wilson Dillaway had come across a group of guys talking about the MTS operating system. While that group didn't seem to be trying to sell anyone else on their work, Wilson was impressed with the discussions that were going on. Thus, MTS was one of the operating systems that RPI evaluated in early 1976.
