The dealer is giving you the run-around, talk to the service guy, they _have_
to have service facilities to be an authorized Amiga dealer and I can't
believe the service guy doesn't know what the pinouts are.
Composite sync is just that, a composite of both the horizontal and vertical
sync signals in 1. Very similar to a standard TV signal, except it has no
video (picture) information…just the sync signals. Separated sync is what
the ST uses (and the Amiga also supplies it via the DB23 on pins 11 (H sync)
and 12 (V sync) where a separate line is used for the horizontal
syncronization signals and another line for the vertical syncronization
signals.
