There are several FORTH Systems for ATARI b-Bit Computers around. Most of this FORTH are FigForth variants, but some are even supported and developed today.
 
Implementations for ATARI 8Bit Computer (6502 CPU):

* X-Forth -- still in development, will become ANSI compatible FORTH someday, file based (with DOS)
* FigForth 1.0d -- old FORTH Version, disk-block based (without DOS)
* FigForth 1.1 -- Enhanced FigForth, disk-block based (without DOS)
