How to find out which point the conductors are connected to. On the memory chips you can see the connection with pin 45, this is A10

No idea, surely I won't take the glue off, try to take a look to an unmodified card or the rendition chip pinout, the layout coming from these oem cards is always the same.

Can any owners of the original Rendition-ready ICR2 post the contents of the INDYFAST.BAT and INDYSAFE.BAT files?

I am trying to reconstruct them from my non-Rendition, retail boxed ICR2 and CART copies, but my CART version doesn't have these batch file equivalents. I think I was able to reconstruct enough of the INDYFAST.BAT from Re: Rendition Verite Thread in order to get DMA mode working, but would like to confirm their contents.

I've modified these but these should be pretty close from Cart Racing:

[EDIT] To run on original hardware or with my wrapper, you don't need any environment variables, running cart.exe or indycar.exe will automatically run in DMA mode.

This environment variable controls dma. Set it to 0 for FIFO mode and 1 for DMA before running the game.
Set SPEEDY3D_DMA=1
For FIFO mode for icr2 you'll also need to set
Set SPEEDY3D=<path to icr2>
This isn't needed for dma mode or for any other Speedy3D game even in Fifo mode.

I did some additional testing tonight. I'm using a patched ICR2 executable (to enable Cyrix support for Rendition) and it appears to run with DMA by default.

Rendition ICR2 does by default.

Is there a good way to make the V21/2200 slow down to V1000 speeds? I'm thinking of getting one and would like the ability to see how the V1000 runs things without paying more than I would for every other V2200 on eBay combined.

Fair experiment, though if we go in that direction I would be interested in having V1000-native calls answerable by V2x00. I own Descent II and am interested in playing with 3D acceleration without having to compromise the cockpit view, plus EF2000 is another title of my interest. That, in my opinion, is the bigger issue when playing Rendition games made specifically for V1000 on a succeeding card; higher speed, if anything, would more likely be an asset.

Yeah, though in my case both would be nice to have, so as to compare the two directly. I assume both would be able to handle the same DirectX games as well, but I might be wrong on that. For just playing games of course the faster card is better and I'd even consider adding cooling to go even higher, but for cataloguing the differences in a controlled environment and not spending $500 it would have been good. I'm sort of surprised there's that much difference in general though, I'd have thought them both being programmable and everything I've heard of the V2x00 saying it's basically a superset of the V1000 would have meant it'd be natively doable, but I guess not.

V1000 was the original template for Direct3D and should be functional up to 5.2 (though I would not expect full feature support past 2.0). Like all devices with proprietary APIs, Rendition is best on what is tuned specifically for it.
