Can anyone tell me if it is possible to upgrade the OMAX DOS software
or changing it to Windows version on the same computer? We have a
500Mhz computer so I think it should be possible to run WinXP on it.
Would it be possible to simply change the harddisk and install Windows
and additionaly OMAX software?

Why do you want to run Windoze? If you *really* want to upgrade, get
eCS from
http://os2.mensys.nl/indexuk.html
or pick up a copy of OS/2 Warp4 on ebay. OS/2 and its derivative, eCS,
run DOS programs better than DOS did and you gain a multi threaded OS.
