| | Acorn Computers - Wikipedia, the free encyclopedia |
 | | Acorn's BBC Micro computer dominated the UK educational computer market during the 1980s and early 1990s, drawing many comparisons with Apple in the U.S. Though the company was broken up into several independent operations in 2000, it leaves an impressive legacy, particularly in the development of RISC personal computers. | | | Even from the time of the Atom, Acorn were considering how to move on from the 6502 processor: the 16-bit Acorn Communicator developed in 1982 using the 65816 being a key example. | | | Acorn Computers was a British computer company established in Cambridge, England, in 1978. |

| | Acorn Atom - Wikipedia, the free encyclopedia |
| | The Acorn Atom was a home computer made by Acorn Computers Ltd from 1981 to 1983 when it was replaced by the BBC Micro (originally Proton) and later the Acorn Electron. | | | The Atom was Acorn's first computer to be aimed squarely at the home market. | | | It had built-in BASIC (Atom BASIC), although in an idiosyncratic version, which included indirection operators (similar to PEEK and POKE) for bytes and words (4 bytes). |

| | Acorn Atom Emulator |
| | The problems is that the key layout of the Acorn Atom differs from those found on current computers, so some remapping had to be done. | | | Since I heard about emulators for various other machines like the Acorn Atom, I have been thinking about writing an emulator, after I discovered that none was available. | | | The Acorn Atom only has three memory mapped I/O-ports for the communication with the hardware. |
