A600 clockport questions

[mongo]

I'm looking at installing 2 clockport based items in my A600.

I'm looking at buying an A603 and using the clockport for the first item, and also one of http://amigakit.leamancomputing.com/catalog/product_info.php?cPath=42&products_id=208
to run the second item.

I'm just not sure on the room the AmigaKit adaptor takes up. Does anyone have a photo handy of one that is actually already installed in an A600 to see exactly what room it needs?

And secondly, is there any hardware/software reason why two clockport device can't be used at once?

It most likely won't work, since both clockports will be mapped into the same location in the Amiga's memory map.
