The composite signals are different on PAL from NTSC.  If you have an adapter that plugs into the RGB connector directly like an old Amiga 520 RF Modulator it will work correclty.  AGA will switch between NTSC and PAL modes properly, however.

Do you mean that the composite signal on a non-AGA Amiga is bound to only one standard even if the computer can display both ?


No.  I am saying that the AGA systems and A600 that came with a built-in composite signal output can only display the colorburst (or chromanence) signal for the standard that it was generated from.

For example:  I had a 1084S monitor for years and used it in both PAL and NTSC modes on my A1200 and it worked fine in either mode.

If I sent my A1200 to England and switched my power supply to 50 Hz it still would not work with the TV sets in England in color because my A1200 has an NTSC composite RF modulator built in.  If I bought a SCART adapter that uses the RGB video outputs on the A1200 then it would work on a SCART TV in PAL mode only even though my system is NTSC.  (Assuming, of course, that I double mouse-buttoned the startup to be PAL and changed the screenmode preferences file.)

If I left my A1200 in my bedroom here in the U.S. and hooked it up to a U.S. TV set it would work but only in NTSC mode.
