Original IBM CGA has ONE RCA jack (for composite
video), NOT TWO.
EGA often has two, and there are some aftermarket CGA boards that have a
color composite and a B&W composite jack.
Clone CGA cards with no RCA sockets sometimes put the composite signal on
pin 7 of the DE9 connector (this is a no-connect on the iBM card). Worth
checking there anyway.
