I saw your post on Amiga.dk, and as PaSha states, it's a 23 pin connector, not 25 pin.
I guess your next question would be something in the lines of "how do I connect it to a monitor", and to save you the efforts, I'll say "you can't" and explain that the modern monitors don't sync down to 15kHz, so you'll have to use a TV and suggest the scart adapter at the
local dealer.
