SIC/XE Assembler.js

What is this?

This is a SIC/XE assembler written in JavaScript. It performs two passes over the input file, first to generate the symbol table and then to generate the object program. It also generates a solution file that contains the symbol table and the object program.

SIC-XE stands for Simplified Instructional Computer Extra Equipment, and is a hypothetical computer system. It is commonly used for instructional use and teaching, and is primarily used and talked about in the textbook, System Software: An Introduction to Systems Programming, by Leland Beck.
