I started at age 8 or 9 on my VIC-20. This was in 1988-89. Later I got a C-64 followed by the Amiga models, and found my way to assembler and along with that a fundamental understanding of how computers work, what's possible and what's not, and how to (in terms of performance) properly and efficiently make computers do what you want them to do.

Commodore computers played a huge part in raising me.
