Hi All, the new Atari800 0.9.8 is most probably the best Atari800/800XL/130XE/5200 emulator. It's developed by several people and ported to many different operating systems. While its features are rich and its compatibility is close to 100%, the documentation is very incomplete and hasn't been updated for a long time. atari800.exe is the standard DOS version of Atari800 apma800.exe is an Allegro version that emulates the digitized sound properly Since this version adds two new directives into Atari800 configuration file I suggest to first call Atari800 with -configure option: atari800.exe -configure You should also try to call it with -help to see the mostly undocumented options. Any volunteer for writting the documentation could contact me at pstehlik@zln.cz Petr Stehlik, 31st Dec 1998
