[net.micro.apple] apple rgb to amdek 500, HELP

Help....

I have been trying to connect an amdek 500 color monitor to an
Applied Eng. RGB card.  So far I have tried two different cables
and have had no success.

Here's whats happening.

I receive the picture but cannot get it to lock. It rolls top to bottom.
By CAREFULL adjustment I can just about get it but not quite. Sounds like
the vertical sync. Problem is that the amdek 500 works in both nstc and rgb
modes. In the nstc mode it works fine. I would guess that the same vertical
sync circuitry works for both ???

Does anyone have a similar setup (especially in Holmdel, so that I could
test to see which component is bad - rgb card, cable, monitor)?

Any advice will be appreciated.

Thanks in advance
