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.

dbpedia-owl:abstract
  • Il Research Machines LINK 480Z fu un microcomputer ad 8 bit prodotto da Research Machines Limited 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 ed 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 cassete 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.

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.
