The rgb cable that hooks to a 1084 monitor has both the 9 pin and the 23 pin.
Yes, but that is for a different revision of the 1084 than the one in the OP's picture.
So if the OP indeed has the 1084 that was in the picture, the cable he needs has a D23 in one end and a DIN6 in the other. You can clearly see the DIN6 above the "lin. RGB" text.
