UCCEL Corp, previously called University Computing Company ("UCC"), was a data processing service bureau on the campus of Southern Methodist University in Dallas, Texas.
[citation needed] By 1972, the company operated a middle-sized datacenter in Troy, Michigan, and a huge facility in Arlington, Texas, based on top-of-the-line IBM/360 (and later IBM/370) processors.
Uccel's "big-ticket item" claim to fame was software called UCC-1/TMS (Tape Management System), an IBM mainframe product for managing the tape library in an OS/MVS operating system environment.
In 1986, UCCEL Corporation purchased Cambridge Systems Group, Inc., which marketed for SKK, Inc. and their market-leading ACF2 mainframe security product.
[citation needed] In June 1987, Uccel was unexpectedly bought out by its archrival, Computer Associates, which aggressively sold directly competing products CA-Dynam/TLMS (tape management), CA-Scheduler and batch job scheduling products originally from Capex Corporation (flagship products "Optimizer" and "TLMS") and Value Software, plus CA-Top Secret (security / mainframe discretionary access control).
