6502 Forth-83 dialect for the Commodore PET 2001
Objectives of this project are, in no particular order:
- (PETTIL) make a Forth that runs on my Commodore PET 2001
- (PETTILmob) find others who are interested in this project
- (PETTILmini) Raspberry Pi PET emulator with a replica keyboard/case
- (PETTILmobile) tour the USA in a bus a vintage computer museum
- create YouTube videos
- improve my "6502 Code Golf" skills
- have fun!
PETTIL is my implementation of the Forth programming language, following the FORTH-83 standard. It has some interesting features.
- PETTIL core
-
- Direct-threaded
-
- 15 clock cycle NEXT
-
- lightweight runtime core, under 6K
-
- virtual memory on cassette tape
-
- built-in Sweet16
- PETTIL studio
-
- interactive developer environment
-
- uses Commodore native screen editor
-
- interpreter editor compiler assembler
- PERTURB test automation
- Tiddlywiki documentation
- obsessively optimized for speed & space
- integration with Rhialto Seibert's KOSMON
- metacompilation
