  • The BBC Master was a home computer released by Acorn Computers in early 1986. It was designed and built for the British Broadcasting Corporation (BBC) and was the successor to the BBC Micro Model B. The Master featured several improvements on its predecessor. The systems had 128 KB RAM as standard, alleviating the shortage of available RAM which had amongst other things discouraged use of the best graphics modes in the original design, and had two cartridge slots mounted above the new numerical keypad. Rather than the MOS Technology 6502 microprocessor used by the Model B it ran on the slightly improved 65SC12: the cost of this CPU compatibility with the Model B was that the address bus was still only 16 bits, meaning that only 64 KB could be directly addressed at any one time and the remaining memory had to be paged in as required. However the 65SC12's extra instructions allowed a little more to be shoehorned into the OS and BBC BASIC ROMs, limited by the memory architecture to 16 KB each. Although the Master was intended to be compatible with "legally written" software for the older models, there were some problems running older programs, particularly games. Conversely, although few programs were ever targeted specifically at Master series machines (except the Master 512), many later BBC games (and Master versions of earlier classics such as Elite) included enhanced features which took advantage of the extra memory.
  • Il BBC Master è un microcomputer prodotto dalla Acorn Computers nel 1986, sucessore del BBC Micro Model B. Rispetto al predecessore, il sistema montava più memoria RAM (128 kb com standard, espandbile fino a 512) e un'evoluzione del processore MOS Technology 6502. Benché fosse mantenuta una certa retrocompatibilità con i modelli precedenti, molti programmi hanno problemi a funzionare correttamente: molti programmatori così si specializzarono a rilasciare versioni corrette dei programmi, adattati al nuovo hardware, aggiungendo allo stesso tempo nuove caratteristiche permesse dalla maggiore quantità di memoria.
