Font Factory
6510 assembler project for Font Factory '89
I developed the Font Factory in 1989 as 'bare metal' 6510 code using a C-64 cartridge. This is a reverse-engineered assembler version of the code published in Volume 2, Number 5 of the Commodore Disk User magazine. The original magazine images are in the doc folder. Enjoy!
