I've got one or two of these things. Mind you, I just moved to another house so it could take a few weeks until I dug it out of the correct box.
I also have a converter the other way round if anyone is interested, it's to connect a 23-pin monitor connector to a 15-pin VGA connector. I used this to connect my Amiga M1438 multiscan monitor to my Cybervision 64/3D. Since I sold that card and my 1438 died I have no use for it anymore.
