If the CPD-1304 monitor works with the Macintosh High-Resolution Video Card
(the current 8-bit display card), there won't be any problem with the Display
Card 8/24GC signals driving the Sony CPD-1304. (We could not verify that the
CPD-1304 monitor works with the Macintosh High-Resolution Video Card, but we do
know that Sony's CPD-1302 monitor works with that card.) However, you will need
to use a different cable to connect the two devices because the cards have
different connectors.
An issue with regard to the cable concerns the sense pins, which tell the card
what type of monitor is attached. For the Sony CPD-1302 monitor, the sense
pins should be configured as below, where 0 = Ground and 1 = Not Ground. To
ground a sense pin, tie it to the C&VSYNC.GND signal.
