Sure, but is there a list or something stating which of them are compatible ?

I know USB was picky, but not Radeon.

:(
"Radeon" is just a marketing name and encompasses very many radically different chip sets.

First of all, you'd have to find a PCI Radeon board, which would be from the noughties, before the change to PCIe, and after the transition from AGP. So, you're probably looking at 2000 - 2005. The 7000, 8000, 9000 series are probably your target.
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

Yes, and they have to be 3.3V and, I think, with a maximum of 128 MB RAM according to R. Czuba's old web site...

Not sure the 8000 series are a go for the CTPCI.

So it almost works!

It detects the card and runs the bios etc:

Then it displays the boot screen on the Radeon and starts to boot:

Until...:

Edit: Seems like it's just incompatible with NVDI. So I need to remove NVDI from the Auto folder. Wow, this thing is fast in gembench!

There is also a 2nd problem, I get a parity error depending on how I position the card, so perhaps there is a bad connection somewhere.

Just to add a couple of final pics.

Here it is, now I need to squeeze it back into the Space Case:

Now I need to find some software other than gembench to run :lol:
