Title: A1200 composite out, color or not?
Post by: vic20owner on September 25, 2005, 03:49:03 AM

I remember my original A1200 having only monochrome composite output.  Now I see that PAL machines have color output. This makes me wonder, was the composite output color all along, but in PAL?  I believe PAL composite signal on an NTSC tv appears in monochrome because the color signal is incompatible.

??? Anyone ???

I just tried it (again) and I get color with my (towerized, Toasterized) NTSC 1200 through the composite out.

(Note: not the Toaster's output, the 1200's built-in output)

The colors look pretty funky, too, when you put a 256-color High-res, laced screen through an LCD monitor! (Samsung SyncMaster 150MP on the composite-in connector).

The A600 and A1200 composite video output is in colour.
As you mentioned, you're probably seeing it in monochrome due to a monitor compatibility problem.

Ahh ok. I don't have my A1200 in front of me (yet). I just remembered it being monochrome... appears I am mistaken (thankfully).

Yep, A1200 has color composite out. BTW. A1000 also has color out, while A500 has monochrome (unless taken from modulator).

Yeah, i think that the only amiga who had a composite monochrome output was the amiga 500 (the built in one).

This is probably the source of my confusion. I owned an A500 before the A1200.

If you try to display an NTSC output on a PAL screen or vice-versa then yes, you'll get a monochrome output usually with a bit of noise or ringing going through it as well.  This is because the two colour systems are incompatable with each other (for a start the colour carrier resides on different frequencies).  Some modern TVs are capable of displaying both NTSC and PAL signals though.
