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
