It is written in java (sorry) and provides a web interface that has:
- a blinken-lighten display for registers
- a memory view with different filters you can apply
- a Gameboy-like game pad
- a console you can use to interact with the computer (including running assembly instructions directly)
- a file browser with an integrated editor for editing file
So everything you need to get going on low level programming.
It includes some sample code, including snake and conway's game of life, in the /src directory.

We have the start of a C compiler for the machine, but that's still a work in progress. We plan on improving the interactivity and visual feedback over the next few months, so any feedback you can give us would be very much appreciated!
