containing 12 CPUs, and saw its first large-scale application at the AT&T Universal Cards credit-card billing center, the first enterprise-scale replacement of mainframes by a UNIX server within AT&T. Both these systems used the MIPS R-series RISC microprocessors. After the WE 32000 microprocessors were canceled, the 3B2 follow-on (codenamed "Phoenix") was also to use a MIPS CPU. The entire MIPS-based product line was to be renamed the System 9000, and to feature "scalavailability" - from normal commercial availability (NCA) choices, to fault-tolerant (FT), to high performance SMP. The System 9000 strategy was canceled when AT&T's Board of Directors decided to close down AT&T-CS, and buy the NCR Corporation, announced in 1991, and implemented January 1, 1992. NCR management tried to cancel all further development of AT&T-CS systems, though some refused to allow this for a few years, and backlash from AT&T Network Systems (later to be spun off as Lucent Technologies) precipitated a purge of NCR upper management by the AT&T Board. NCR had just developed and suddenly canceled its Motorola 88000-based systems, and then started the NCR 3000 series, developed using Intel x86 microprocessors. The AT&T StarServer E could still beat the comparably equipped NCR 3450 by 11% in the TPC Benchmark B test, and some of the SSE's 7 patented innovations were then adapted and retrofitted into the NCR 3000 design. NCR was renamed AT&T Global Information Solutions (AT&T-GIS) in 1994, and some of the top NCR management was purged. The Naperville, IL operation provided LifeKeeper Fault Resilient System software (a failover high-availability software cluster product), the Distributed lock manager for Oracle Parallel Server, and the Vistium computer-telephony integrated (CTI) on-line hardware-assisted networked meeting product. Only about 400 employees remained in the Naperville location by the beginning of 1995. In the mid-1980s, there had been something like 30,000 employees associated with AT&T-CS, including marketing, customer support, factories, and development. In 1994 a high powered team from AT&T Naperville transferred to NCR San Diego in the midst of developing a Micro Channel architecture based four channel SCSI adapter based on a custom ASIC. This host bus adapter went on to great success in NCR and served as a connection point for over a billion dollars worth of peripherals attached to NCR minicomputers and database servers. On September 20, 1995, Bob Allen, AT&T Chairman of the Board and CEO, announced the "trivestiture" - the 3-way split of AT&T into the
