The platform/atari/ directory is used for targeting an Atari 8-bit computer. Most things are shared between the 6502-based targets so please consult cpu/6502/README for further details. The following Atari 8-bit Ethernet card is supported: - Atari 8-bit Ethernet Project: Use driver cs8900a.eth with address $D500. The 'disk' make goal requires HiassofT's dir2atr program. It is available at http://www.horus.com/~hias/atari/ - either as source code (being part of the 'AtariSIO driver and utilities for Linux') or as Win32 binary program (being part of the 'Atari Tools for Win32').
