While nine models were eventually produced with the BBC brand, the term '''BBC Micro''' is usually colloquially used to refer to the first six (Model A, B, B+64 and B+128, Master 128, Master Compact), with the subsequent models considered as part of the [[Acorn Archimedes|Archimedes]] series.
===BBC Master===
In 1986, [[Acorn]] followed up with the BBC Master, which offered memory sizes from 128 KB and many other refinements which improved on the 1981 original. At heart it was essentially the same 6502-based BBC architecture, with many of the upgrades that the original design had intentionally made possible (extra ROM software, extra paged RAM, second processors) now included on the circuit board as internal plug-in modules.
