I posted the design files at http://sdz-mods.com/index.php/2024/05/20/voodoo-4400h/ , but I'll attach them here as well.
Also posted various assembly options (without extra RAM, without HDMI output).

The archive contains the editable schematic and PCB files, PDF schematic, GERBER files, BOM, P&P files, PCI bracket dxf, and the FPGA bitstream and MCS file for the flash used. After I cleanup the code a bit, I'll upload that as well.

The DIP switches enable or disable the extra 2MB FBI RAM and 2MB TMU RAM. These can be set always to enabled, and the extra memory can be disabled from autoexec.bat.

That is so amazing !

Why no HDMI passthrough ? 😉 (just kidding)

I thought about it, but then I'll have to make HDMI addons for 2D cards, also there was no space for another connector (and stacking the connectors and making a 2 slot V1 card would be silly).

Such a very lovely card! Any plans to make V1 as SLI version or a beast as your Voodoo 2 4444SX?

Wow that's a beautiful card. Seriously amazing work thank you for sharing.

@Rabanik Thanks! Yes, there will be a card very similar to the Voodoo 2 4444SX.
@chrismeyer6 Thank you!

I wonder, what is the chip used for VGA switching ? I recently looked at some analog switch chips for HDMI etc. and thought they could be used for basically anything and the one I notice on this card seems like it is one such.
Excellent work on all the 3DFX things I see here ~

That's exactly what it is 😀
TS3DV642, intended for HDMI2.0/DP1.4 applications, but it works fine for VGA switching.

So they do work fine for that too 🤣. Now I know what I will use for high resolution analog video switching in some totally unrelated application (upgrades to a projector I am messing with) ~
