About 1967, IBM convinced Columbia to retire its 7090-series mainframes in favor of IBM's new, but not quite ready yet, supercomputer, the IBM 360/92 (that's not a typo). The 360/50 was loaned (rented) to us to serve until the new monster was ready. When it finally arrived about a year later, it was called the 360/91.
