This emulator was built using the EMF system, designed and implemented by Steven Goodwin, between 2011 and 2020.
First, the machine is defined with a custom description language. Each component part, along with its interactives, it's explained in a human-friendly, and machine-readable, format.
Then, this description is processed to generate an emulator, assembler, and dissembler for the machine in question. This can be in any language, but is currently targetted to JavaScript.
Finally, these files are glued into the JavaScript EMF framework, which handles the UI-specific components.

Initialising
TIP: Untick the 'Update' option to improve performance
TIP: Some browsers require human interaction before they play sound. So try clicking, and refreshing the page, if you hear nothing
This emulator runs a simple 'Hello World' program, from an in-built tape. To watch it in action, simply press 'Stop', then 'Reset', and 'Step' your way through it.
