I have seen wikipedia claiming that the Enterprise machines had version of some of the Dizzy games!!!

http://en.wikipedia.org/wiki/Fantasy_World_Dizzy

Is this actually true? I thought the machines were long dead by the time Dizzy came to power in the late 80s?

If it is true - where can I get a copy of the game to run on my machine

Yes, but these not are official released games, these are unofficial conversions of the Spectrum version.
The Enterprise is about the third most populated 8 bit computer in Hungary (after the Zx Spectrum and C64), and have a very active life until about 1995. And it is still alive in 2008 
The enthusiastic Hungarian EP users converted least thousand Spectrum programs to the Enterprise, including the Dizzy series
