Floating Point Systems Inc. (FPS) was a Beaverton, Oregon vendor of attached array processors and minisupercomputers. The company was founded in 1970 by former Tektronix engineer Norm Winningstad, with partners Tom Prince, Frank Bouton and Robert Carter. Carter was a salesman for Data General Corp. who persuaded Bouton and Prince to leave Tektronix to start the new company. Winningstad was the fourth partner.
The original goal of the company was to supply economical, but high-performance floating point coprocessors for minicomputers. In 1976, the AP-120B array processor was produced. This was soon followed by a unit for larger systems and IBM mainframes FPS AP-190. In 1981, the follow-on FPS-164 was produced, followed by its big brother, the 264 having the same architecture. This was 5 times faster using ECL instead of TTL chips.
These processors were widely used as attached processors for scientific applications in reflection seismology, physical chemistry, NSA cryptology and other disciplines requiring large numbers of computations. Attached array processors were usually used in facilities where larger supercomputers were either not needed or not affordable. Hundreds if not thousands of FPS boxes were delivered and highly regarded. FPS's primary competition up to this time was IBM (3838) and CSPI.
Cornell University led by physicist Kenneth G. Wilson made a supercomputer proposal to NSF with IBM to produce a processor array of FPS boxes attached to an IBM mainframe with the name lCAP.
