It's kind of interesting that the A600 trapdoor memory expansion slot carries all the signals of the Denise chip and more to be able to make such an expansion possible.  I wonder what Commodore was planning when they came up with this design?

The indivision ECS doesn't use the Denise, it can be plugged into even the Paula socket. Just look at the A1000 adapter for it :-)


It doesn't use Denise for the A600 (it does for the 500/2000, from what I've heard - won't boot without them installed), but it still has to be getting the video signal data in the A600 from somewhere, right?  And the only way it could know what pixels to put where is going to have to be coming through the trapdoor slot...
