I know this ain't GS but it's relevant: I have one //c with an Irish/UK
motherboard, a second //c with a US board that replaced a failed Irish one
(I swapped-in the character ROM from the failed board so that shift-3 gives
the pound character, not the hash character). Composite video out on the
Irish board is PAL, on the US board it is NTSC. When hooked up to a PAL
monitor with composite colour input (Philips CM3388 II), the NTSC board
gives better, cleaner colour with less ripple than the PAL board. When
using the NTSC board with a _monochrome_ display, the ripple on the video
quickly becomes annoying whereas the PAL board shows almost no ripple at
all. Is there any sort of autodetection built-in to the //c? How come I get
better colour on a PAL monitor from a NTSC board?
