as6502 -- A 6502 Cross Assembler


This is a version of the 6502 cross assembler originally written by J. H. Van Ornum.

This version supports the undocumented instructions of the 6502 and writes raw binary files.  It's written in C and the archive includes source code and a 16-bit DOS executable.

Download the archive (25 KB).
