Hack Emulator
This project emulates Hack computer from
nand2tetris course. It is still under light
development (light means that I might add/fix/polish things from time to time,
but not actively).

Current features
-
Built-in assembler (although it is very crude and doesn’t really have error
reporting as of yet) -
ROM view, including binary machine code as well as the coresponding
instructions. Current instruction (program counter) is highlighted. -
RAM view
-
Full ALU implementation, which includes undocumented instructions, unlike the
official CPU emulator. -
Adjustable clock speed (although I would not recommend to go above ~10MHz)
-
Full support for keyboard input and display output.
-
All in your browser on any device! No Java required!
Kinda Maybe Sorta Planned features:
-
Breakpoints
-
Ability to modify values in RAM
-
Running official test files
-
Ahead of time compilation as well as other optimizations
-
Perhaps some extensions to Hack, like
-
Memory banks
-
Colored display
-
Periferals like storage?
-
6/N-key rollover support
-
-
Light/dark theme support?
Building
To build the project you need Node 12.x. Then you can just run:
npm install
npm run-stript build
This should create app.js file in ./dist/. You can open ./dist/index.html
in your browser.
Contributing
Ha, like anyone ever will!
Some other notes
This project was mostly written in about a week to get some practice with
TypeScript and React (given that I’ve not used either before), so there might
be some rough edges or non-idiomatic code/project structure. Reviews are
welcome!
