Indivision AGA Mk3 - Major difficulties.

I have not gotten the Indivision AGA Mk3 to work properly for more than a few seconds. I've read the docs and most of the threads here. Removed the unit a couple of days ago, because it was causing glitching on the RGB output. Reinstalled today, and it doesn't cause RGB issues today, but it still doesn't work correctly with HDMI output.

Always defaults to an 800x600 display, not matter what I configure it to do. Jumps to either half-screen width, or double size randomly. Also OSD flickers constantly, and randomly enters live-config mode on it's own - unless I unplug the CIA card cable.

I can't figure out what is going on. The cards are fully seated down to the motherboard.

Thanks for any help. I'll provide more info as requested, rather than write too much now.

[Update]

I've got it stable in one screen mode now... not as good as it was once, but at least I can read the text of the config tool! I still have to leave the CIA board disconnected. Can't adjust other screen modes without screwing this one up.

I had the CIA adapter installed in the wrong orientation. I'll figure the rest out... docs are lacking in that area!

Quote from Jens

I included pictures of the CIA adapter in the right place. What else should the documentation say or show? Should it say "please look at the pictures"?

The photo was dark, and I only made out the main board, perhaps a close-up of the CIA like you did with the Lisa. Afterward, I did go back and look at the photo closer and could see the CIA adapter.

If I'm the only one who has done this, then don't change anything! It's just my old eyes.

There's also a pdf here on the site with the instructions.

That would have helped! Having the colour made it clear.
