Seems he was able to solve DMAC problem, both, ide and CDROM are working! Awesome news, that gives me hope to see TF534 tunning on CDTV one day...

Its more likely to be a 536.. The 534 is not getting touched again.

Shame his stuff is closed source and you can't build one yourself, and that he doesn't share any info back to the community :(
That board also doesn't have a CPU and is CDTV specific, so there could be some cheats involved that a more general accelerator (proper) couldn't get away with.
I'll see if I can do some testing on the weekend with my TF534+A570 - I think the answer is close!

The DMAC stuff will all be bus grant related. Similar to the Atari ST
