I haven't got one myself, but I have a prometheus, which works well - except for the lack of drivers. That is why I am seriously considering a mediator myself for my A4000T.
Anyone own one care to comment on how the Mediator boards are? Do the drivers work well and is the speed ok?
With sound cards and playing back mp3 files - does it take up alot of the 68k cpu time? or not?
thanks!
