-Atari
-=====
-
-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.md for further details.
-
-The following Atari 8-bit Ethernet card is supported:
-
-- Dragon Cart: 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').
