I need to know what version (language) my Mega has. I have a wrong version of WordUp 3.0 (yup, won't start with a wrong version, I would really like to know why they did it that way. Could it be the ability to work without GDOS etc.) I suppose there is a address somewhere in ROM where I could peek, but what is it. Thanks, Markku (jackin@vehka.uta.fi)

The OS Header contains information about the TOS you are running, including the country (language, keyboard) you have. That value is found in the WORD at offset $1c from the address _sysbase points to; it's called "os_conf" for "OS configuration." The least-significant bit of this word is 0 for NTSC and 1 for PAL. The next four bits (at least) encode the country the OS was built for: VALUE COUNTRY 0 USA 1 Germany 2 France 3 UK 4 Spain 5 Italy 6 Sweden 7 Switzerland, French language ("Swiss/French") 8 Switzerland, German language ("Swiss/German") 9 Turkey 10 Finland 11 Norway 12 Denmark Other values may mean other things in the future; no tight promises there. For that matter, this word may lose most of its meaning if, in future, a single set of ROMs contains the keyboard and language for many countries. Those issues will be decided when they arise. ============================================ Opinions expressed above do not necessarily -- Allan Pratt, Atari Corp. reflect those of Atari Corp. or anyone else. ...ames!atari!apratt
