From the project

AT65C02 Hobby Computer

ATOS Software Released! The main software suite for AT65C02 is now available in the Software_ATOS directory. ATOS (AT65C02 Operating System) provides a complete ROM-based monitor (SMON), interactive shell, trace/debugging commands, loadable program support, and integrated EhBASIC. The codebase has been extensively cleaned up and optimized with comprehensive documentation. This is now the recommended primary software for the AT65C02 platform.
