Welcome to world of
8-bit computers Atari XE/XL.
This is RASTER's Atari XE/XL small English page. Sorry, but all my other
Atari pages are written mainly in Czech language. My English isn't so good, but you find
some short-only documentation here anyhow. If you want to know more about next
and other stuff, you must try to read in Czech, as well as I'm trying to write in English.
