About: LINK 480Z

An Entity of Type: device, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The LINK 480Z was an 8-bit microcomputer produced by Research Machines Limited in Oxford, England, during the early 1980s. The 480Z used a Z80 microprocessor with up to 256 KB of bank-switched RAM. The system could be used as a stand-alone unit with cassette-based storage and the BASIC programming language run from ROM, or it could boot CP/NOS (a network version of CP/M) over a local area network from a file server. When fitted with an optional external floppy disk drive the system could boot the CP/M operating system directly.

  • The LINK 480Z was an 8-bit microcomputer produced by Research Machines Limited in Oxford, England, during the early 1980s. The 480Z used a Z80 microprocessor with up to 256 KB of bank-switched RAM. The system could be used as a stand-alone unit with cassette-based storage and the BASIC programming language run from ROM, or it could boot CP/NOS (a network version of CP/M) over a local area network from a file server. When fitted with an optional external floppy disk drive the system could boot the CP/M operating system directly. The 480Z was sold mainly to the UK educational market as cassette-based system or as a diskless node which could be connected, via the proprietary CHAIN Network, to a Research Machines 380Z acting as a file server.

  • Il Research Machines LINK 480Z è un microcomputer a 8 bit prodotto da Research Machines Limited (Oxford, Gran Bretagna) e commercializzato dal 1981 al 1985. Erede del Research Machines 380Z del 1977, anche il LINK 480Z era basato sul microprocessore Zilog Z80A a 4 MHz ma, rispetto al primo, presentava importanti novità, fa cui l'adozione di un case contenente sia la circuiteria interna che la tastiera, fino a 256 KB di RAM e una scheda grafica (opzionale) capace di risoluzioni più elevate. Il computer poteva essere utilizzato sia come un normale personal computer, usando l'interprete BASIC residente in ROM come sistema operativo e caricando i programmi con il lettore di cassette incorporato oppure poteva essere caricato il CP/NOS (una versione specifica del CP/M per le reti) tramite rete locale (LAN) direttamente da un file server. Se era presente l'unità dischi il LINK 480Z poteva lanciare direttamente il CP/M. Come il 380Z, anche il LINK 480Z era destinato principalmente al settore didattico/educativo e fu perciò venduto soprattutto alle scuole britanniche come sistema che poteva essere connesso, tramite la rete proprietaria CHAIN, ad un 380Z che fungeva da file server.
