This is a figFORTH 1.1 port originally distributed by W. F. Ragsdale for the Rockwell AIM65 back in the late seventies. Will has taken this listing and made a port to the Apple I/Replica I, resulting in a powerful programming environment for experimentation or computer control applications. FORTH is still popular today and is found in such diverse applications as embedded controllers and PDA's to NASA applications on the Space Shuttle! Written in machine code.
