Radio Shack TRS-80 Acoustic Modem
Radio Shack, ZDA
- Opis:
- Akustični modem model TRS-80. [SLO]: Akustični modemi so bili prve naprave, ki so omogočale povezovanje računalnikov preko telefonskih linij, preden je internet postal razširjen. Uporabniki so na svojem telefonu zavrteli številko in nato slušalko položili v akustični sklop modema, ki je digitalne signale pretvoril v zvočne valove za prenos. Ti modemi so se povezovali z Bulletin Board Systems (BBS). Za razliko od sodobnega interneta je bila povezava z BBS podobna obisku posamezne, samostojne spletne strani, pri čemer je vsak BBS ponujal svojo edinstveno vsebino in skupnost. Če je bil BBS v ZDA, so morali uporabniki zavrteti ameriško številko za povezavo. Ta metoda je bila ključni korak v evoluciji digitalnih komunikacij, saj je omogočila zgodnjo izmenjavo podatkov in spletne skupnosti. Akustični sklop TRS-80, ključna periferna naprava za serijo računalnikov TRS-80, ki jo je proizvajala Tandy Corporation, je imel utilitaristično in funkcionalno zasnovo. Sklop je imel pravokotno, škatlasto obliko, običajno v sivi ali bež barvi, ki je ustrezala estetiki računalnikov TRS-80. Njegova najbolj prepoznavna značilnost je bila par gumijastih čašic na vrhu, zasnovanih za varno držanje slušalke standardnega telefona. Te čašice so bile nameščene tako, da so se uskladile z earpiece (zvočnikom) in mouthpiece (mikrofonom) slušalke, kar je zagotavljalo tesno prileganje za natančen prenos zvočnih signalov. [ENG]: Acoustic modems were the first devices used to connect computers over phone lines, before the internet became widespread. Users dialed a number on their telephone, then placed the handset into the modem's acoustic coupler, which converted digital signals into sound waves for transmission. These modems connected to Bulletin Board Systems (BBS). Unlike the modern internet, connecting to a BBS was akin to visiting a single, standalone website, with each BBS offering its unique content and community. If the BBS was in the US, users had to dial a US number to connect. This method was a crucial step in the evolution of digital communications, enabling early data exchange and online communities. The TRS-80 Acoustic Coupler, an essential peripheral for the TRS-80 computer series produced by Tandy Corporation, featured a utilitarian and functional design. The coupler had a rectangular, box-like shape, typically in a grey or beige color, matching the aesthetic of the TRS-80 computers. Its most distinctive feature was the pair of rubber cups on the top, designed to securely hold the handset of a standard telephone. These cups were positioned to align with the earpiece and mouthpiece of the handset, ensuring a snug fit to facilitate the accurate transmission of audio signals.
