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)
- Learn-Forth – Subset of FigForth from HOFACKER (Order No.7053), disk-block based (without DOS) as well on cassette
- Power-Forth – Extended FigForth from HOFACKER (Order No.7055), disk-block based (without DOS)
- Antic Forth 1.4s – very powerfull ANTIC Forth, disk-block based (without DOS)
- QS-Forth 1.0 – QS-Forth, disk-block based (without DOS)
- Mesa FORTH – Mesa FORTH
- Graphic FORTH – A ANTIC Forth 1.4s with special extensions, mostly in german language
- ES Forth – English Software Company FORTH, file-based FORTH (with DOS)
- SNAUT – A FORTH 83 comaptible Standard FORTH. The only trace of this FORTH is an advertising in a german magazin for now
- Yet another Target Compiler – Target Compiler for creating MAC/65 Source from FORTH
