but are now mainly assembled in New York and Mexico. The IBM 3740 Data Entry System was developed at the facility in 1973 and the follow-on IBM 5280 Distributed Data System had its beginnings there as well, but was transferred in 1981 to the Austin, TX facility, where it was released for production. The advent of personal computing swallowed up this type of data entry by 1990. The IBM 5110 personal computer was developed and manufactured in the facility. IBM Rochester played an important in the Summit and Sierra supercomputers. RS/6000, now System p, and hard disk development also occurred at this site in the past. Distinctions The AS/400 division at the plant received the Malcolm Baldrige National Quality Award in 1990. In November 2004, the facility claimed the top spot in the TOP500 list of fast supercomputers with a prototype Blue Gene/L system containing 32,768 processors. It clocked in at 70.72 teraflops. The manufacturing output of the site is so great that if it were a separate company, it would be the world's third-largest computer producer. The plant, which is near U.S. Highway 52 in the northwestern part of Rochester, was recognized in 1990 by the National Building Museum as one of the significant contributions of IBM to the built environment of the United States, along with IBM's New York City headquarters and the IBM building in Atlanta, Georgia. Tenants Hitachi Global Storage Technologies, although having been spun off from IBM Storage Technology, remains on-site, leasing otherwise unused space from IBM. Along with the Mayo Clinic, the IBM plant is one of the biggest employers in the Rochester area, reportedly numbering around 5,000 in 2002. In 2019, Crenlo LLC rented part of the IBM facility to move part of its EMCORE manufacturing division, where it is currently separate from the Crenlo Cab Manufacturing line of products, as EMCORE was sold in 2021.
