#1 I cannot use it with my towerized Amiga 1200 because that machine has an Indivision in it and the boards occupy the same physical space. Understand that if you have an Indivision you CANNOT USE this hardware. This should be clearly marked on AmigaKit's product page but it isn't
I also have a FastATA IV as well and have been anticipating getting a Indivision MK II in the future.
I asked this very question and I'm under the impression that this might be possible (even in a Desktop A1200) if you use ROM risers to elevate the FastATA over the Indivision. In my last order to Amigakit I ordered the ROM risers as well as one for the clockport.
