Bummer! :mad: This is very bad news. It had to be internally! :furious: All hope is floating away for CDTV & A2000 users. :pissed:
It was never supposed to work in the CDTV, as the CDTV uses DMA for its CD-ROM (and on top of that there is very little space above the 68k-socket).
A2000 could get away with a simple adapter to the MMU (turbo-slot) only question is wether you'd still be able to use Z2 cards (as the ACA won't provide a config-out signal).
But Jens also hinted at an "ACA2000", which might just be the same card minus A500-side-slot plus some logik for Z2 use (just my guess).
