A PC speaker is a loudspeaker built into some IBM PC compatible computers. The first IBM Personal Computer , model 5150 , employed a standard 2.25 inch magnetic driven (dynamic) speaker. [ 1 ] More recent computers use a tiny moving-iron or piezo speaker instead. [ 2 ]
The Gigatron TTL is a retro-style 8-bit computer, where the CPU is implemented by a set of TTL chips instead of a single microprocessor, imitating the hardware present in early arcades. Its target is the computing enthusiasts, for studying or hobby purposes. [2] Assembled Gigatron kit computer in display case.
The DB25 is used for multi-track recording and other multi-channel audio, analog or digital (ADAT interface (DB25)), and was the standard connector for IBM compatible PC printer connection before USB and other connections became popular. It offered 8 simultaneous data pathways to the printer.
Generally use coaxial cable types such as RG-6 and RG-59 (except for twin-lead). Belling-Lee/IEC 169-2 connector TV aerial plug (a.k.a. antenna plug) Television antenna connection for most video devices outside North America. Used by early home computers and game consoles to connect them to TVs because of the lack of any other connector.
Top: normal connection. Bottom: bi-wiring. Loudspeaker bi-wired using banana plugs. Bi-wiring is a means of connecting a loudspeaker to an audio amplifier, primarily used in hi-fi systems. Normally, there is one pair of connectors on a loudspeaker and a single cable (two conductors) runs from the amplifier output to the terminals at the ...
This connector's color indicates it should plug into a computer's line audio out socket Any number of 3.5 mm sockets for input and output may be found on personal computers , either from integrated sound hardware common on motherboards or from insertable sound cards .
Speaker wire is a passive electrical component described by its electrical impedance, Z.The impedance can be broken up into three properties which determine its performance: the real part of the impedance, or the resistance, and the imaginary component of the impedance: capacitance or inductance.
The electric signaling levels are handled by a driver circuit external to the UART. Common signal levels are RS-232, RS-485, and raw TTL [1] for short debugging links. Early teletypewriters used current loops. It was one of the earliest computer communication devices, used to attach teletypewriters for an operator console.
