Opis:
Umazano bel računalnik z vgrajeno tipkovnico. [SLO]: Commodore računalniki so izjemni primeri iz obdobja domačih računalnikov v osemdesetih letih, pogosto imenovani tipkovniški računalniki zaradi svoje zasnove, ki je celoten računalnik vgradila v ohišje tipkovnice. Ti stroji so bili običajno prodajani brez monitorjev in povezani s televizorji, kar je bila praktična in stroškovno učinkovita rešitev, ki je uporabnikom prihranila stroške ločenega monitorja. Commodore računalniki, skupaj s konkurenti, kot je ZX Spectrum, so igrali ključno vlogo pri omogočanju dostopa do računalnikov širši javnosti. Pojavili so se v času, ko je postajalo običajno imeti domači računalnik, množična proizvodnja pa je bila v vzponu. Commodore 128, naslednik legendarnega Commodore 64—najbolje prodajanega računalnika osemdesetih let—je bil predstavljen leta 1985. Imel je preoblikovano ohišje z izboljšano tipkovnico, vključno z numerično tipkovnico in funkcijskimi tipkami. Pomnilnik je bil razširjen na 128 KB RAM-a, kar je navdihnilo njegovo ime. C128 se je ponašal z ločenim grafičnim čipom, ki je omogočal izboljšan video izhod v primerjavi z originalnim C64. Poleg tega je vključeval Zilog Z80 CPU, ki mu je omogočal delovanje operacijskega sistema CP/M, kar mu je zagotovilo eno izmed najobsežnejših knjižnic programske opreme med konkurenti. [ENG]: Commodore computers are notable examples from the era of home computers in the 1980s, often referred to as keyboard computers due to their all-in-one design, which integrated the entire computer into a keyboard housing. These machines were typically sold without monitors and connected to televisions, a practical and cost-effective solution that saved users the expense of a separate monitor. Commodore computers, alongside rivals like the ZX Spectrum, played a pivotal role in making computers accessible to the general public. They emerged at a time when owning a home computer became commonplace, and mass production was on the rise. The Commodore 128, successor to the iconic Commodore 64—the best-selling computer of the 1980s—was introduced in 1985. It featured a redesigned case with an improved keyboard, including a numeric keypad and function keys. The memory was expanded to 128 KB of RAM, which inspired its name. The C128 boasted a separate graphics chip, offering enhanced video output over the original C64. Additionally, it included a Zilog Z80 CPU, enabling it to run the CP/M operating system, giving it one of the most extensive software libraries among its competitors.
