MOS Technology 6532
The 6532 RAM-I/O-Timer (RIOT) was an integrated circuit made by MOS Technology, as well as second sources such as Rockwell. It incorporates 128 bytes of static RAM, two bidirectional 8-bit digital input/output ports, and a 8-bit Programmable interval timer (with pre-divider). This high degree of integration made it popular in the late 1970s and early 1980s, as it could take the place of several different integrated circuits (ICs). It is used in the Atari 2600 video game console. The chip was also deployed in Gottlieb pinball machines, such as ''Haunted House'' and ''Black Hole'', the Atari 810 and 1050 disk drives, as well as Commodore's 8050, 8250 & 8250LP PET disk drives. The Atari 850 Interface, which gives the Atari 400 and 800 computers an RS-232 interface, uses two 6532 chips. 6532 ICs were available in 1 MHz The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event (or cycle) ...

Gottlieb
Gottlieb (formerly D. Gottlieb & Co.) was an American arcade game corporation based in Chicago, Illinois. It is best known for creating a vast line of pinball machines and arcade games (including ''Q*bert'') throughout much of the 20th century. History Gottlieb's main office and plant was at 1140-50 N. Kostner Avenue until the early 1970s, when a new modern plant and office were opened at 165 W. Lake Street in Northlake, IL. A subassembly plant was also built in Fargo, ND. The company was established by David Gottlieb in 1927 with his brother Sol, and initially produced only pinball machines. In October 1932 the company moved to a factory four times the size of its previous one. It later expanded into various other games, including pitch-and-bats, bowling games, and eventually video arcade games (notably '' Reactor'', ''Q*bert'' and ''M*A*C*H*3''.) Like other manufacturers, Gottlieb first made mechanical pinball machines, including the first successful coin-operated pinball ...

Computer Form Factor
Form factor is a hardware design aspect that defines and prescribes the size, shape, and other physical specifications of components, particularly in electronics. A form factor may represent a broad class of similarly sized components, or it may prescribe a specific standard. It may also define an entire system, as in a computer form factor. Evolution and standardization As electronic hardware has become smaller following Moore's law and related patterns, ever-smaller form factors have become feasible. Specific technological advances, such as PCI Express, have had a significant design impact, though form factors have historically evolved slower than individual components. Standardization of form factors is vital for hardware compatibility between different manufacturers. Trade-offs Smaller form factors may offer more efficient use of limited space, greater flexibility in the placement of components within a larger assembly, reduced use of material, and greater ease of transportat ...

Hertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event (or Cycle per second, cycle) per second. The hertz is an SI derived unit whose formal expression in terms of SI base units is 1/s or s−1, meaning that one hertz is one per second or the Inverse second, reciprocal of one second. It is used only in the case of periodic events. It is named after Heinrich Hertz, Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. For high frequencies, the unit is commonly expressed in metric prefix, multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RS-232
In telecommunications, RS-232 or Recommended Standard 232 is a standard introduced in 1960 for serial communication transmission of data. It formally defines signals connecting between a ''DTE'' (''data terminal equipment'') such as a computer terminal or PC, and a ''DCE'' ('' data circuit-terminating equipment'' or '' data communication equipment''), such as a modem. The standard defines the electrical characteristics and timing of signals, the meaning of signals, and the physical size and pinout of connectors. The current version of the standard is ''TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange'', issued in 1997. The RS-232 standard had been commonly used with serial ports and serial cables. It is still widely used in industrial communication devices. A serial port complying with the RS-232 standard was once a standard feature of many types of computers. Personal computers used them ...

Atari 8-bit Computers
The Atari 8-bit computers, formally launched as the Atari Home Computer System, are a series of home computers introduced by Atari, Inc., in 1979 with the Atari 400 and Atari 800. The architecture is designed around the 8-bit MOS Technology 6502 CPU and three custom coprocessors which provide support for sprites, smooth multidirectional scrolling, four channels of audio, and other features. The graphics and sound are more advanced than most of its contemporaries, and video games are a key part of the software library. The 1980 first-person space combat simulator ''Star Raiders'' is considered the platform's killer app. The Atari 800 was positioned as a high-end model and the 400 as more affordable. The 400 has a pressure-sensitive, spillproof membrane keyboard and initially shipped with a non-upgradable of RAM. The 800 has a conventional keyboard, a second cartridge slot, and allows easy RAM upgrades to 48K. Both use identical 6502 CPUs at ( for PAL versions) and coprocess ...

Commodore PET
The Commodore PET is a line of personal computers produced starting in 1977 by Commodore International. A single all-in-one case combines a MOS Technology 6502 microprocessor, Commodore BASIC in read-only memory, keyboard, monochrome monitor, and, in early models, a cassette deck. Development of the system began in 1976, and it was demonstrated and sold as the first personal computer for the masses at the January 1977 Consumer Electronics Show. The name "PET" was suggested by Andre Souson after he saw the Pet Rock in Los Gatos, and stated they were going to make the "pet computer". It was backronymed to Personal Electronic Transactor. In a 1995 retrospective, ''Byte'' magazine—and subsequently many others—referred to the PET, Apple II and TRS-80 collectively as the "1977 trinity" of pioneering personal computers. Following the initial PET 2001, the design was updated through a series of models with more memory, better keyboard, larger screen, and other modifications. ...

Commodore 8050
The Commodore 8050, Commodore 8250, and Commodore SFD-1001 are 5¼-inch floppy disk drives manufactured by Commodore International, primarily for its 8-bit CBM and PET series of computers. The drives offered improved storage capacities over previous Commodore drive models. They are notable for the disk drive having twice the processing power than the connected computer in having two 1MHz 6502 processors sharing operation of communication and disk operation, though only supporting 4k of main memory. The disk operating system is actually contained within the disk drive unit with commands being sent via the 8 bit GPIB interface where the system decodes the message and carries out the requested operation such as formatting a disk without further involvement from the connected computer. Specifications All three models utilize 5¼-inch double-density floppy disks with a track spacing of 100 tracks-per-inch, for a total of 77 logical tracks per side. Data is encoded using Commodore' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commodore International
Commodore International Corporation was a home computer and electronics manufacturer with its head office in The Bahamas and its executive office in the United States founded in 1976 by Jack Tramiel and Irving Gould. It was the successor company to Commodore Business Machines (Canada) Ltd., established in 1958 by Tramiel and Manfred Kapp. Commodore International (CI), along with its U.S. subsidiary Commodore Business Machines, Inc. (CBM), was a significant participant in the development of the home computer industry, and at one point in the 1980s was the world's largest in the industry. The company released its first home computer, the Commodore PET, in 1977; it was followed by the VIC-20, the first ever computer to reach one million units of sales. In 1982, the company developed and marketed the world's best selling computer, the Commodore 64; its success made Commodore one of the world's largest personal computer manufacturers, with sales peaking in the last quarter of 1983 at ...

Atari 8-bit Computer Peripherals
Atari 8-bit computer peripherals include floppy drives, printers, modems, and video game controllers for Atari 8-bit computers, which includes the 400/800, XL, XE, and XEGS. Because the Atari 400/800 8-bit computers were bundled with an RF modulator, stringent FCC regulations limiting radio emissions applied. Consequently, the Atari 400/800 systems internal construction use large metal frames as Faraday cages to prevent emissions. This prevents the use of internal cards to add connections for peripherals. To permit easy expansion, Atari developed the SIO (Serial Input/Output) bus. This bus daisy chains together all Atari peripherals into a single string. The Atari computer family was designed to be easy for novice users to expand, with one universal connector plug. Peripherals have their own IDs and can deliver downloadable drivers to the computer during the boot process. However, the additional electronics in these "intelligent" peripherals made them cost more than the "dumb" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Hole (pinball)
''Black Hole'' is a pinball game released in 1981 by Gottlieb. It is notable for having two playfields: one on top with a conventional slope, and one mounted underneath, sloping away from the player. It has no connection with the 1979 film of the same name. Description ''Black Hole'' was the first machine to feature a lower playfield viewed through a window in the upper playfield. It was touted as the highest-grossing pinball game of all time shortly after its release, partly due to (or despite) the fact that it was the first pinball game which cost 50¢ to play (although many argue that Williams ''Black Knight'', and ''Firepower'' were already at 50¢ before the release of Black Hole). Black Hole's robotic speech is generated by a Votrax SC-01. Features *2 playfields *6 flippers *6 pop bumpers *4 drop target banks *1 spinner *Rotating disc animated backglass *Infinity backglass lighting *Multiball *Speech (Votrax SC-01) Game quotes * "Do you dare to enter the Black Hole?" * " ...

Haunted House (pinball)
''Haunted House'' is a pinball game released in October 31 1982 by Gottlieb. It was the first game with three playfields that the ball can move between, including one below the main playing surface. ''Haunted House'' was designed by John Osborne, with artwork by Terry Doerzaph. It is part of Gottlieb’s “System 80” series of pinball machines. Description ''Haunted House'' has three playfields (a mini underground playfield, a main playfield, and an upper playfield.), eight flippers, at unique angles, four pop bumpers, two kick-out holes, a secret passage (a false target that drops down after impact to allow entrance to cellar.), a trap door that opens for ball, a lightning animation in the backglass and kicking bat targets. The lower playfield of ''Haunted House'' is accessible any time during the game, and the ball(s) can travel between all three playfields. Each playfield is themed to be a part of a haunted house, the main level being the main floor, the lower level being th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
