@Franko (sorry I must have missed your mediator post)
I'm running a Blizzard 060/PPC and Mediator setup and I must say its awesome!
I've got a Soundblaster 128 and a Voodoo 5 5500 hooked up to it. With the update patch OS4 runs with this setup right out of the box in RTG.
I'm personally looking forward to OS4.1 as I'm sure there will be a lot more options for it software wise as OS4 is a little thin on the ground.
I also use Amigasys4AGA and Classic Workbench P96 along with my RTG setup and they both look and run great.
I also have a stock OS3.9 setup running off the Blizzard SCSI which is nice and fast plus WarpOS/Warp3D all setup and working with the Voodoo 5.
I'm glad I got my PPC, I know it cost me an arm and a leg but I feel part of a very exclusive club and surprisingly I'm not at all worried about using it, I switch the machine on and use it daily.
Steve.
