Interactive assembler and simulator for the 8080 CPU. Can be used from the command line (on Node.js) or in the browser, with a simple UI):
A live version can be played with at http://eliben.org/js8080
The code for the assembler and simulator is in the src/ directory.
The files parser.js and assembler.js implement a 8080 assembler. Assemblers
typically have different syntaxes; this one attempts to remain close to the
"Intel 8080 Assembly Language Programming Manual" book. Not all directives are
implemented - PRs welcome!
The file sim8080.js is the 8080 simulator; it is forked from
https://github.com/maly/8080js with some minor tweaks, and retains its original
BSD license.
For an example of using the assembler and simulator from the command line, see
sample/sample.js.
js-8080-sim uses browserify; see Makefile for the invocation.
The files index.html, ui.js and js8080simBundle.js should be distributed
together to make it all work in the browser.
