"Apple presentation system" cable problem

[Shnomoe]

Ok, so i bought an apple presentation system, which in the description, said that it had vga cables to hook up to your monitor. when i got it today, it has some kind of old vga that is really wide, and nothing like the vga that i was thinking of. I cant even find a picture of it online, but i did find a picture of an apple presentation system with an adapter for the cable, but i dont know what its called. Heres the link to the picture

If you need me to take a picture of what the cable looks like to help me, i will, but does anyone know whats going on?

Is it one of these connectors?
DVI? (may have more pins than the one shown in the color picture).
D-sub 25, D-sub 37, or D-sub 50? (outdated technology)
SCSI? (in its many incarnations; outdated technology)
VGA?

Thanks to your d-sub article, after looking into it is something called DB-15, and i think i can find an adapter for it!
Thanks so much!
