UTEC UTEC was a computer built at the University of Toronto (UofT) in the early 1950s. It was one of the first working computers in the world, although only built in a prototype form while awaiting funding for expansion into a full-scale version. This funding was eventually used to purchase a surplus Manchester Mark 1 from Ferranti in the UK instead, and UTEC quickly disappeared. The name was an acronym for "University of Toronto Electronic Computer".

Programmed Data Processor Programmed Data Processor (PDP), referred to by some customers, media and authors as "Programmable Data Processor, is a series of minicomputers made and marketed by the Digital Equipment Corporation from 1957 to 1990. The name "PDP" intentionally avoids the use of the term "computer" because, at the time of the first PDPs, computers had a reputation of being large, complicated, and expensive machines, and the venture capitalists behind Digital (especially Georges Doriot) would not support Digital's attempting to build a "computer"; the word "minicomputer" had not yet been coined. So instead, Digital used their existing line of logic modules to build a "Programmed Data Processor" and aimed it at a market that could not afford the larger computers.

UNIVAC Solid State The UNIVAC Solid State was a magnetic drum-based solid-state computer announced by Sperry Rand in December 1958 as a response to the IBM 650. It was one of the first computers to be (nearly) entirely solid-state, using 700 transistors, and 3000 magnetic amplifiers (FERRACTOR) for primary logic, and 20 vacuum tubes largely for power control. It came in two versions, the Solid State 80 (IBM-style 80 column cards) and the Solid State 90 (Remington-Rand 90 column cards). In addition to the "80/90" designation, there were two variants of the Solid State -- the SS I 80/90 and the SS II 80/90. The SS II series included two enhancements -- the addition of 1,280 words of core memory and support for magnetic tape drives. The SS I had only the standard 5,000-word drum memory described in this article and no tape drives.

Timex Sinclair 1000 The Timex Sinclair 1000 (TS1000) was the first computer produced by Timex Sinclair, a joint venture between Timex Corporation and Sinclair Research. It was launched in July 1982, with a US sales price of US$99.95, making it the cheapest home computer to date; it was advertised as "the first computer under $100". The computer was aimed at regular home users. Unlike earlier computers aimed at home users, the TS1000 was not a kit which had to be soldered and assembled. As purchased, the TS1000 was fully assembled and ready to be plugged into the users' home TV (which served as a video monitor). The TS1000 was a slightly-modified version of the Sinclair ZX81 with an NTSC RF modulator, designed for use with North American TVs, instead of the UK PAL RF modulator which was used for units sold in Portugal. The TS1000 doubled the onboard RAM from 1 KB to 2 KB. The TS1000's casing had slightly more internal shielding but remained the same as Sinclair's, including the membrane keyboard. It had black-and-white graphics and no sound. It was followed by an improved version, the Timex Sinclair 1500 which had substantially more RAM (16 KB) and a lower price (US$80). However, the TS1500 did not achieve market success, given that the marketplace was by this time dominated by Commodore, RadioShack, Atari and Apple.

Philco computers Philco was one of the pioneers of transistorized computers. After the company developed a surface barrier transistor, much faster than previous point-contact types, it was awarded contracts for military and government computers. Commercialized derivatives of some of these designs became successful business and scientific computers. The TRANSAC (Transistor Automatic Computer) Model S-1000 was released as a scientific computer. The TRANSAC S-2000 mainframe computer system was first produced in 1958, and a family of compatible machines, with increasing performance, was released over the next several years.

PERQ The PERQ, also referred to as the Three Rivers PERQ or ICL PERQ, was a pioneering workstation computer produced in the late 1970s through the early 1980s. In June 1979, the company took its very first order from the UK's Rutherford Appleton Laboratory and the computer was officially launched in August 1979 at SIGGRAPH in Chicago. It was the first commercially produced personal workstation with a Graphical User Interface. The design was heavily influenced by the original workstation computer, the Xerox Alto, which was never commercially produced. The origin of the name "PERQ" was chosen both as an acronym of "Pascal Engine that Runs Quicker," and to evoke the word "perquisite".

UNIVAC 1101 The ERA 1101, later renamed UNIVAC 1101, was a computer system designed and built by Engineering Research Associates (ERA) in the early 1950s and continued to be sold by the Remington Rand corporation after that company later purchased ERA. Its (initial) military model, the ERA Atlas, was the first stored-program computer in the U.S. that was moved from its site of manufacture and successfully installed at a distant site. Remington Rand used the 1101's architecture as the basis for a series of machines into the 1960s.

SEAC (computer) SEAC (Standards Eastern Automatic Computer" or Standards Electronic Automatic Computer") was a first-generation electronic computer, built in 1950 by the U.S. National Bureau of Standards (NBS) and was initially called the "National Bureau of Standards Interim Computer", because it was a small-scale computer designed to be built quickly and put into operation while the NBS waited for more powerful computers to be completed (the DYSEAC). The team that developed SEAC was organized by Samuel N. Alexander. SEAC was demonstrated in April 1950 and in May 1950 it went into full production, making it the first fully functional stored-program electronic computer in the US.

TX-0 The TX-0, for Transistorized Experimental computer zero, but affectionately referred to as tixo (pronounced "tix oh"), was an early fully transistorized computer and contained a then-huge 64K of 18-bit words of magnetic core memory. The TX-0 was built in 1955 and went online in 1956 and was used continually through the 1960s at MIT. The transistorized TX-0 computer used 3600 transistors in its computer's circuitry and had also used the Philco high-frequency surface-barrier transistors in its design. In 1953, Philco had developed the world's first high frequency surface-barrier transistor, which was also the first transistor that was suitable for high speed computers. The TX-0 and its direct descendant, the original PDP-1, were platforms for pioneering computer research and the development of what would later be called computer "hacker" culture.
