So I'm trying to trace the RGB/S connections on this motherboard. I found the RGB signals going into the 343S1091 Antelope ramdac, but the composite sync is going into the 343s0164-a MemCjr memory controller. So I'm guessing the H/V comes from the Antelope ram dac, but I'm not able to trace is out. Does anyone know where the sync is on antelope ramdac? I looked online and on Apple Computer Custom IC Definitions it says these chips are pin to pin compatible with the quadra 700/950 and it seems sync is on the RAMDAC 357S0010-A on pin 40. However pin 40 doesn't seem to be connected on the Antelope cause I get nothing out of it? Anyone have any suggestions? Thanks!
