As far as I know I can have both a Mediator 4000Di MK2 with a Radeon and a CVPPC installed at the same time so that I can use the Radeon for OS 4.1 and the CVPPC for OS3.9 and Warp3D.
My question is: Would I be able to use some of the RAM from the Radeon under OS3.9? Not as video RAM but as normal fast RAM?
And does anybody have any experience with such a setup?
I had that setup for a day and realized that the CVPPC was slower that the Radeon and redundant. I use my MK2 for original Classic Amiga stuff in both OS's and the Radeon for the rest. As far as having 2 displays, I had no interest; but it works (well one at a time in OS4,1). I mean, what would you do with that? It is one thing in a Toaster setup using TV monitors, but they are composite.
The ram thing is usable in OS 3.9 (too slow for 4.1) since neither OSs use more than a fraction of the Radeon's ram; the Warp3d works with the Radeon except for a few games like Wipe Out 2097, but an extra $$$ chunk of hardware for a couple of games? I guess whatever floats your boat.
