@ hap: Going through the English version right now and making some changes here and there. It's mostly some simple grammar adjustements, but also finding alternatives to convey the original meaning of typical Dutch expressions and references as aptly as possible.
For instance, I replaced "THE GLASSES OF LEE TOWERS" with "ELTON JOHN'S GLASSES", to make it more inter-culturally. 
I agree that a final proofread by a native speaker wouldn't hurt.
EDIT: Done editing the English version. Would you guys please have a look at it?
@JohnHassink: Thanx John, like I posted earlier, the main goal is too get a proper tramnslated version, so I did the kickoff and now it's time to put the dot on the i 
@hap: Lee towers ... ofcourse And you are right, Elton John would be better, since only a small group of MSX-ers knows Lee Towers is a dutch singer and the majority knows who Elton John is
Haha, good one, Better change it to $ then
