Sad news for 2013
If ACA500 does not work with Blizzard (including PPC i guess) and Apollo boards, it means no 68060 beastie for the A500. If even cheap old accelerators like the MTEC 1230 don't work, it leaves us only with the ACA12xx boards: why not build directly a 520 or 530 accelerator, or even better 540 or 560?
I guess i won't be the only one to be disappointed by the replacement of the IDE port by a CF port.
Not sure that, as such, the ACA500 would be more interesting than older A500 expansions (except for people with nothing so far).
