Texas Instruments SN76477
SN76477 " complex sound generator" is a sound chip produced by Texas Instruments (TI). The chip came to market in 1978, and TI ceased production of the part. A compatible version is identified as ICS76477.BG-Micro lists ICS76477 Sound Generator. The chip is typically used as a sound effects generator in arcade games and toys and for hobby projects. The use of the SN76477 in a musical context is limited by the fact that it was difficult to electronically control the pitch of the produced sound.SN-Voice: discussion of ...

Voltage Divider
In electronics, a voltage divider (also known as a potential divider) is a passive linear circuit that produces an output voltage (''V''out) that is a fraction of its input voltage (''V''in). Voltage division is the result of distributing the input voltage among the components of the divider. A simple example of a voltage divider is two resistors connected in series, with the input voltage applied across the resistor pair and the output voltage emerging from the connection between them. Resistor voltage dividers are commonly used to create reference voltages, or to reduce the magnitude of a voltage so it can be measured, and may also be used as signal attenuators at low frequencies. For direct current and relatively low frequencies, a voltage divider may be sufficiently accurate if made only of resistors; where frequency response over a wide range is required (such as in an oscilloscope probe), a voltage divider may have capacitive elements added to compensate load capacitance. ...

Interact Home Computer
The Interact Home Computer (also called The Interact Family Computer) is a 1978 American home computer made by Interact Electronics Inc of Ann Arbor, Michigan. It sold under the name "Interact Model One Home Computer". The original Interact Model One computer was designed by Rick Barnich and Tim Anderson at 204 E. Washington in Ann Arbor, then moving to the Georgetown Mall on Packard St. in Ann Arbor. Interact Electronics Inc was a privately held company that was funded by Hongiman, Miller, Swartz and Cohn, a law firm out of Detroit. The President/Founder of Interact Electronics Inc was Ken Lochner, who was one of the original developers of the BASIC language based out of Dartmouth College. Ken had started Interact Electronics Inc after founding the successful computer time-sharing company Cyphernetics in Ann Arbor, which was purchased by ADP in 1975.

ABC 80
The ABC 80 (Advanced BASIC Computer 80) was a personal computer engineered by the Swedish corporation Dataindustrier AB (DIAB) and manufactured by Luxor in Motala, Sweden in the late 1970s and early 1980s. It was introduced on the market in August 1978. The ABC 80 was based on an earlier modular computer system from the same company and built around a Z80 and of ROM containing a fast semi-compiling BASIC interpreter. It had of RAM as main memory and a dedicated (included) tape recorder for program and data storage, but could also be expanded to handle disk drives as well as many other peripherals. The ROM could be extended in increments of 1 or 4KB in order to handle such so called "options". The monitor was a black and white TV set modified for the purpose, an obvious choice since Luxor also made TVs. The ABC 80 was used in schools and officies around Scandinavia and parts of Europe. It was also used for industrial automation, scientific measurement and control systems. Lik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Musical Instrument
An electronic musical instrument or electrophone is a musical instrument that produces sound using electronic circuitry. Such an instrument sounds by outputting an electrical, electronic or digital audio signal that ultimately is plugged into a power amplifier which drives a loudspeaker A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A ''speaker system'', also often simply referred to as a "speaker" or ..., creating the sound heard by the performer and listener. An electronic instrument might include a user interface for controlling its sound, often by adjusting the pitch (music), pitch, frequency, or duration of each Musical note, note. A common user interface is the musical keyboard, which functions similarly to the keyboard on an acoustic piano, except that with an electronic keyboard, the keyboard itself does not make any sound.

Remco
Remco Industries, Inc. was a toy company in the United States founded in the 1940s. It was best known for toys marketed and sold in the late 1950s and early 1960s, like the 'Johnny Reb Cannon', 'Mighty Matilda Atomic Aircraft Carrier', 'Remco Voice Control Kennedy Airport' (which featured model airplanes of American, TWA and United Airlines, a record player and an album which played a voice giving landing and take-off instructions) and the tethered 'Electronic Falcon Plane' that "flies itself". The company's slogan was "Every Boy Wants a Remco Toy...And So Do Girls!" History Remco was founded by two cousins, Isaac "Ike" Heller and Saul Robbins. Armand Daddis soon joined the two as the company gradually moved from simple 'walkie-talkies' to a variety of sophisticated remote control toys. The name Remco comes from the two words "Remote Control". Originally located in Newark, NJ, the company later moved to nearby Harrison, New Jersey. The boxes and toys were printed with just the ...

Gakken EX-System
The Gakken EX-System is a series of educational electronics kits produced by Gakken in the late 1970s. The kits use denshi blocks (also known as ''electronic blocks'') to allow electronics experiments to be performed easily and safely. Over 25 years after its original release, one of the main kits from the series was reissued in Japan in 2002. History A brief timeline: ; 1972: Gakken and Denshi Block Mfg. Co. Ltd. collaborate to release denshi block kits under Gakken's name. ; 1976: The EX series was released. ; 1981: The successor to the EX series, the FX series, is released. ; 1986: Gakken stops producing denshi block kits. ; 2002: The EX-150 is reissued in Japan, and is successful enough to justify the production of an expansion kit. ; 2011: Gakken releases a small kit compatible with the EX-system, #32 in their "Otona no Kagaku" mook series.

Educational Toy
Educational toys (sometimes also called "instructive toys") are objects of play, generally designed for children, which are expected to stimulate learning. They are often intended to meet an educational purpose such as helping a child develop a particular skill or teaching a child about a particular subject. They often simplify, miniaturize, or even model activities and objects used by adults. Although children are constantly interacting with and learning about the world, many of the objects they interact with and learn from are not toys. Toys are generally considered to be specifically built for children's use. A child might play with and learn from a rock or a stick, but it would not be considered an educational toy because 1) it is a natural object, not a designed one, and 2) it has no expected educational purpose. The difference lies in perception or reality of the toy's intention and value. An educational toy is expected to educate. It is expected to instruct, promo ...
