jsbeeb – a Javascript BBC micro computer emulator

jsbeeb is a BBC micro computer emulator written in Javascript (runnable in a browser window).

Created by Matt Godbolt, it is based on Tom Walker’s b-em emulator (a huge thanks to him for open sourcing his code). The disc loaded up by default is the amazing Elite (made available by Ian Bell).

The source code is on GitHub. jsbeeb works best in Chrome or Firefox. It is still very much a work in progress. Cycle-accurate emulation is greatly helped by the fantastic Visual 6502 Project.
