Arxon Scandoubler, but no image

[tone007]

Is a little shaky image though, even after trying the jumpers in different modes.

That one doesn't flicker-fix, are you using an interlaced or non-interlaced mode?

They've mislabeled the card, then.  It only scandoubles, but non-interlaced modes (such as A4000 bootup menu) should be solid.

I was unhappy with mine and find the C= 2320 works much better (scandoubles and flicker-fixes.)

Or do you say: get rid of both and use: http://www.vesalia.de/e_indivisionaga4000d.htm

The Indivision AGA 4000 is a much better device than any of the old-style ones, though since you have an RTG you won't benefit much from the HighGFX AGA screenmodes.
