By Matt Godbolt. Based on Sarah Walker's b-em emulator. Huge thanks to her for open sourcing her
code. Big thanks too to Richard Talbot-Watkins for his help and support. The disc loaded up by
default is the amazing Elite (thanks to
Ian Bell for making it available).
Source is on GitHub. Works best in Chrome
Cycle-accurate emulation greatly helped by the fantastic Visual
6502 Project. Consider donating to them if you enjoy this stuff as much as I do!

This is an emulator for the BBC Micro
Model B, a popular home computer in the UK in the 1980s.
The default disc image is Elite - a pioneering 3D space trading game. To boot discs on the BBC,
one would press SHIFT and BREAK. The keyboard
of the BBC is slightly different from a modern PC, notably in the placement of the symbol
characters. Also, the current keyboard layout is optimized for a US keyboard; I am working on
improving this situation.
