40 or so years ago, IBM certified OS/MVT as functionally complete (or stable?) and stopped enhancing it. Source code was still available back then. A subset of IBM's mainframe customers kept using the last release of MVT for many years, as their management was not prepared to incur the expense of upgrading both processors and operating system in order to stay current with IBM's moving window of currency. Continuing to use the old, no longer officially maintained operating system was called "paddling your own canoe". At SHARE meetings, the principal spokesman for this concept was Dr. Robert Rannie, who would carry a large wooden canoe paddle on his shoulder throughout the SHARE week. Google for "share os/mvt project ibm "wooden paddle"" and read the first four hits. A copy of that version of MVT is still available and still works on certain computers.
