Foonly
Foonly Inc. was an American computer company formed by Dave Poole in 1976, that produced a series of ''DEC PDP-10'' compatible mainframe computers, named ''Foonly F1'' to ''Foonly F5''. The first and most famous Foonly machine, the ''F1'', was the computer used by Triple-I to create some of the computer-generated imagery in the 1982 film ''Tron''. History At the beginning of the 1970s, the Stanford Artificial Intelligence Laboratory (SAIL) began to study the building of a new computer to replace their ''DEC PDP-10 KA-10'', by a far more powerful machine, with a funding from Defense Advanced Research Projects Agency (DARPA). This project was named "''Super-Foonly''", and was developed by a team led by Phil Petit, Jack Holloway, and Dave Poole. The name itself came from FOO NLI, an error message emitted by a PDP-10 assembler at SAIL meaning "FOO is Not a Legal Identifier". In 1974, DARPA cut the funding, and a large part of the team went to DEC to develop the ''PDP-10 model KL10'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Information International, Inc
Information International, Inc., commonly referred to as Triple-I or III, was an early computer technology company. Background The company was founded by Edward Fredkin in 1962 in Maynard, Massachusetts. It then moved (serially) to Santa Monica, Culver City, and Los Angeles California. Triple-I merged with Autologic, Inc. in 1996, becoming Autologic Information International Inc. (AIII). The combined company was purchased by Agfa-Gevaert in 2001. In the early 1960s, Information International Inc. contributed several articles by Ed Fredkin, Malcolm Pivar, and Elaine Gord, and others, in a major book on the programming language LISP and its applications. Triple-I's commercially successful technology was centered around very high precision CRTs, capable of recording to film; which for a while were the publishing industry's gold standard for digital-to-film applications. The company also manufactured film scanners using special cameras fitted with photomultiplier tubes as the image ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tron
''Tron'' (stylized as ''TRON'') is a 1982 American science fiction action-adventure film written and directed by Steven Lisberger from a story by Lisberger and Bonnie MacBird. The film stars Jeff Bridges as Kevin Flynn, a computer programmer and video game developer who is transported inside the software world of a mainframe computer where he interacts with programs in his attempt to escape; it also stars Bruce Boxleitner, David Warner, Cindy Morgan, and Barnard Hughes. ''Tron'', along with ''The Last Starfighter'', has the distinction of being one of cinema's earliest films to use extensive computer-generated imagery (CGI). The inspiration for ''Tron'' dates back to 1976, when Lisberger became intrigued with video games after seeing ''Pong''. He and producer Donald Kushner set up an animation studio to develop ''Tron'' with the intention of making it an animated film. To promote the studio itself, Lisberger and his team created a 30-second animation featuring the first appeara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Systems Concepts
Systems Concepts, Inc. (now the SC Group), was a company co-founded by Stewart Nelson and Mike Levitt focused on making hardware products related to the DEC PDP-10 series of computers. One of its major products was the SA-10, an interface which allowed PDP-10s to be connected to disk and tape drives designed for use with the channel interfaces of IBM mainframes. Later, Systems Concepts attempted to produce a compatible replacement for the DEC PDP-10 computers. "Mars" was the code name for a family of PDP-10-compatible computers built by Systems Concepts, including the initial SC-30M, the smaller SC-25, and the slower SC-20. These machines were marvels of engineering design; although not much slower than the unique Foonly F-1, they were physically smaller and consumed less power than the much slower DEC KS10 or Foonly F-2, F-3, or F-4 machines. They were also completely compatible with the DEC KL10, and ran all KL10 binaries (including the operating system) with no modificatio ...

DEC PDP-10
Digital Equipment Corporation (DEC)'s PDP-10, later marketed as the DECsystem-10, is a mainframe computer family manufactured beginning in 1966 and discontinued in 1983. 1970s models and beyond were marketed under the DECsystem-10 name, especially as the TOPS-10 operating system became widely used. The PDP-10's architecture is almost identical to that of DEC's earlier PDP-6, sharing the same 36-bit word length and slightly extending the instruction set (but with improved hardware implementation). Some aspects of the instruction set are unusual, most notably the ''byte'' instructions, which operate on bit fields of any size from 1 to 36 bits inclusive, according to the general definition of a byte as ''a contiguous sequence of a fixed number of bits''. The PDP-10 was found in many university computing facilities and research labs during the 1970s, the most notable being Harvard University's Aiken Computation Laboratory, MIT's AI Lab and Project MAC, Stanford's SAIL, Computer Ce ...

Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megabyte
The megabyte is a multiple of the unit byte for digital information. Its recommended unit symbol is MB. The unit prefix ''mega'' is a multiplier of (106) in the International System of Units (SI). Therefore, one megabyte is one million bytes of information. This definition has been incorporated into the International System of Quantities. In the computer and information technology fields, other definitions have been used that arose for historical reasons of convenience. A common usage has been to designate one megabyte as (220 B), a quantity that conveniently expresses the binary architecture of digital computer memory. The standards bodies have deprecated this usage of the megabyte in favor of a new set of binary prefixes, in which this quantity is designated by the unit mebibyte (MiB). Definitions The unit megabyte is commonly used for 10002 (one million) bytes or 10242 bytes. The interpretation of using base 1024 originated as technical jargon for the byte SI prefix, mult ...

Emitter-coupled Logic
In electronics, emitter-coupled logic (ECL) is a high-speed integrated circuit bipolar transistor logic family. ECL uses an overdriven bipolar junction transistor (BJT) differential amplifier with single-ended input and limited emitter current to avoid the saturated (fully on) region of operation and its slow turn-off behavior. As the current is steered between two legs of an emitter-coupled pair, ECL is sometimes called ''current-steering logic'' (CSL), ''current-mode logic'' (CML) or ''current-switch emitter-follower'' (CSEF) logic. In ECL, the transistors are never in saturation, the input and output voltages have a small swing (0.8 V), the input impedance is high and the output impedance is low. As a result, the transistors change states quickly, gate delays are low, and the fanout capability is high. In addition, the essentially constant current draw of the differential amplifiers minimises delays and glitches due to supply-line inductance and capacitance, and the complement ...

Transistor–transistor Logic
Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors. Its name signifies that transistors perform both the logic function (the first "transistor") and the amplifying function (the second "transistor"), as opposed to earlier resistor–transistor logic (RTL) and diode–transistor logic (DTL). TTL integrated circuits (ICs) were widely used in applications such as computers, industrial controls, test equipment and instrumentation, consumer electronics, and synthesizers. After their introduction in integrated circuit form in 1963 by Sylvania Electric Products, TTL integrated circuits were manufactured by several semiconductor companies. The 7400 series by Texas Instruments became particularly popular. TTL manufacturers offered a wide range of logic gates, flip-flops, counters, and other circuits. Variations of the original TTL circuit design offered higher speed or lower power dissipation to allow design optimization. TTL devices were original ...

Central Processing Unit
A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. This contrasts with external components such as main memory and I/O circuitry, and specialized processors such as graphics processing units (GPUs). The form, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the fetching (from memory), decoding and execution (of instructions) by directing the coordinated operations of the ALU, registers and other co ...

Million Instructions Per Second
Instructions per second (IPS) is a measure of a computer's processor speed. For complex instruction set computers (CISCs), different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic. Many reported IPS values have represented "peak" execution rates on artificial instruction sequences with few branches and no cache contention, whereas realistic workloads typically lead to significantly lower IPS values. Memory hierarchy also greatly affects processor performance, an issue barely considered in IPS calculations. Because of these problems, synthetic benchmarks such as Dhrystone are now generally used to estimate computer performance in commonly used applications, and raw IPS has fallen into disuse. The term is commonly used in association with a metric prefix (k, M, G, T, P, or E) to form kilo instructions per second (kIPS), million instructions p ...
