@Odin:
The only way (AFAIK) to stick an A3/4000 accelerator on an A1200 is via the Micronik Z3i A1200 Zorro3 backplane. And this board most likely has a whole lot of glue logic (and doesn't give you Zorro3 DMA), since the A1200 trapdoor slot only has Zorro2 signals (because of the 68EC020 having a 24bit adress bus) whereas the A3/4000 cpu-slot has Zorro3 signals.
