Yes but there is one problem, CDTV extended ROM uses many non-existing 33C93 registers.. Either there is something else than real 33C93 or there is something else mapped to those addresses.
My plan is to remove CDTV extended ROM (I hope it is socketed) to prevent all Kickstart CDROM accesses and then poke controller addresses until something interesting happens.
Of course I need real CDTV first
