Iskra Delta 4850
Iskra Delta, Jugoslavija
- Opis:
- Samostoječa omara sestavljena iz večih komponent. Zgoraj "GCR CacheTape", spodaj procesor Digital VAX 11/751. K omari spada še 5 kovinskih stranic. [SLO]: Iskra Delta 4850 je zgodnji računalniški sistem iz Slovenije, ustvarjen s strani zgodovinsko pomembnega podjetja Iskra Delta. Ta sistem se je pojavil v obdobju "miniračunalnikov" v 70. in 80. letih prejšnjega stoletja. Ti miniračunalniki, približno velikosti hladilnika, so bili manjši od računalnikov, ki so zasedali celotno sobo ali več sob. Termin "miniračunalnik" poudarja pomembno velikost profesionalnih računalnikov tistega časa. Čeprav so manjši računalniki obstajali, so bili redki, nezadostno zmogljivi in nepraktični za profesionalno in poslovno uporabo. Iskra Delta je, delujoča predvsem v Sloveniji, takrat delu Jugoslavije, izkoristila edinstveno geopolitično pozicijo Jugoslavije. Kljub socialističnemu režimu Jugoslavija ni bila del vzhodnega bloka, kar je omogočalo dostop do zahodne in ameriške strojne opreme. Kot rezultat je bil sistem Iskra Delta 4850 zgrajen okoli računalnika DEC VAX-11/750 z 3,125 MHz CPU-jem na več velikih ploščah. Vključeval je tri Fujitsu M2284N enote s fiksnim diskom (po 168,5 MB vsaka), Fujitsu M2294N enoto s fiksnim diskom (335,54 MB), Cipher M990 enoto za magnetne trakove in domače izdelano napajanje. Računalniški sistem je bil nameščen na dveh stolpih, kjer sta bivala računalnik in njegov "trdi disk," ki je uporabljal velike, težke kartuše—v bistvu ogromne magnetne trakove v ustreznih ohišjih—dostopne preko določenih predalov. Ta velik računalnik so uporabljali številni uporabniki preko računalniških terminalov. Ti terminali, ki spominjajo na sodobne računalniške monitorje in tipkovnice, so bili zaslončki samo za besedilo, ki so pošiljali in prejemali besedilo iz računalnika. Takšni terminali so bili prav tako izdelani v Sloveniji. Podatki in programi so se prebirali z magnetnih trakov, kar je omogočilo delovanje računalnika. [ENG]: The Iskra Delta 4850 is an early computer system from Slovenia, assembled by the historically significant company Iskra Delta. This system emerged during the era of "minicomputers" in the 1970s and 1980s. These minicomputers, roughly the size of a refrigerator, were smaller than the room-sized or multi-room computers that preceded them. The term "minicomputer" highlights the substantial size of professional computers at the time. While smaller computers existed, they were rare, underpowered, and unsuitable for professional and business applications. Operating primarily in Slovenia, then part of Yugoslavia, Iskra Delta leveraged Yugoslavia's unique geopolitical position. Although socialist, Yugoslavia was not part of the Eastern Bloc, allowing access to Western and American hardware. As a result, the Iskra Delta 4850 system was built around a DEC VAX-11/750 computer with a 3.125 MHz CPU on multiple large boards. It included three Fujitsu M2284N Fixed Disk Units (168.5 MB each), a Fujitsu M2294N Fixed Disk Unit (335.54 MB), a Cipher M990 Magnetic Tape Drive, and a domestically made power supply. The system's two towers housed the computer and its "hard drive," which used large, heavy cartridges—essentially huge magnetic tapes in proper casing—accessible via designated drawers. This large computer was shared among multiple users through computer terminals. These terminals, resembling modern desktop computer monitors and keyboards, were text-only display devices that sent and received text from the computer. Such terminals were also manufactured in Slovenia. Data and programs were read from magnetic tapes, facilitating the computer's operations.
