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.

-
-
-
- lightweight runtime core, under 6K
-
- virtual memory on cassette tape
-
- PETTIL studio
-
- interactive developer environment
