Is this possible? I have an original A1300 genlock (with mods from an old
Amazing computing), and I would like to use it with my 2000.

I've hooked a short (less than a foot) ribbon cable to the tower board, 
with a 23 pin connector on the other end. I have the service booklet for 
the A1300, and all my connections were based on the information in it.

When I turn my Amiga on, the system doesn't boot, presumably because the
external clock input is screwed up somehow. In the "direct" mode, I can see
the external video on my monitor, but it has black horizontal bands running
through it. In any other mode ("computer only" or "combined"), I get a blank
screen.

Checking the signals as suggested in the service guide, most seem to
be ok. However, the external clock seems to be very noisy (round, not
square). Is the cable length a problem? Am I getting noise on that line from
the other signals?

Are there other things I should check, or should I give up hope?
