I'm using an old Mac 15-pin-to-VGA adapter that I had lying around. The
15-pin input definitely supports 15kHz, though you have to change one
of the settings in the menu to enable it. I can't read Japanese but
from what I could tell it is mentioned in the manual.

Yes I tried it, using the same cable I made for use with the XRGB-2+.
It works, but doesn't provide any better picture than the 15-pin. My
XRGB-3 came with a note saying that the Japanese 21-pin connector is
not compatible with SCART, though they use the same physical connector.
I only mention it so that others would be aware that SCART cables might
not be usable.
