Re: My CDTV Nightmare
Its more likely to be a 536.. The 534 is not getting touched again.

Re: My CDTV Nightmare
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!

Re: My CDTV Nightmare
The DMAC stuff will all be bus grant related. Similar to the Atari ST
