So today I picked up a Macintosh IIcx.  It is fairly beat up, its missing a hard drive but it seems to make the chime at least when powered on.
 

 
However it has the weirdest video card.  On the card its labeled as a Grayscale Video Card.
 


I have very little experience with desktop Macs, does anyone have a video converter they can sell me? So I can use a regular VGA monitor.

If not if you could at least tell me what this video port is called so I can find it on ebay.

Thanks
