New adapters are made in Russia. Some are sold from ebay, but the price is a bit steep: https://www.ebay.com/itm/1pcs-Adapter-AGP-to- … bwceL:rk:1:pf:0
I have one of those, it works well with 3dfx and S3 AGP cards.

I was going to post that link earlier but ended up doing other stuff instead.

eBay/MasterCard has a promo going on now. $10 off $30 if you pay with a MasterCard. The promo code is: MASTERCARD

Seller only has 2 left for sale right now because I ended up ordering one.

70 dollars for that adapter from russia is just too much
i wish there were other options, seems that they are the only ones selling that so they put that price

Pretty much... but you have to take into account the cost of R&D as well as the manufacturing of the PCBs, the other components, and the time it takes to assemble them. If this is a one man operation and those are being assembled by hand, you can't really expect them to work for nothing.

The PCB design looks like it is probably not multi-layer from the way the traces are on both sides of the board so it probably wouldn't be that difficult to make a new/improved design.. but I doubt the cost would be much less in the end.

hey cyclone, you live in USA?
how much does it cost to send from russia to usa?

its easy to make clones of this adapter.

I'm pretty sure we can make a "Vogons Edition"

I was charged $10 shipping.

Not quite the same, but it should work for Voodoo cards at least.

That one doesn't show PCI-X support and there are also not as many jumpers/options that you can set.

but it should work for Voodoo cards at least

Listed adapter won't work with anything outside of 3dfx and early AGP cards reliably. I've tried some GeForce cards on a 440BX board - black screen after driver install.

I also have one. Came with a small collection of 3dfx cards I once bought from someone who stopped collecting. I have tested it after the purchase and also found it was a bit flimsy and not working on every board or with every card. But it worked fine with a 3dfx voodoo5 5500 agp. Never used it and also don't have a use for it as I have all the pci cards I need. Can't sell it tough, beeing a hoarder and all.... 🤣

The big culprit of such an adapter is the fact that it doesn't fit in a case and is only useful for a test setup (unless you create a modified bracket like someone on Vogons did).

PCI or AGP riser cable and mount the card elsewhere. Easy enough to do that.

As for compatibility, as far as I understand it, only these types of cards will work with such an adapter.. but I will have to test to verify when the adapter actually arrives. I'll also try to do some testing with a 66Mhz PCI / PCI-X slot.

AGP 1.0
Universal AGP
Universal AGP 3.0

Basically any cards that can fall back to 1x and can use 3.3v - but I am pretty sure that some cards with those specifications will not work with a PCI adapter.

Here is a good page about the different versions of AGP.
http://www.playtool.com/pages/agpcompat/agp.html

I think another big reason why only some early AGP cards and Voodoo cards are compatible with these adapters is the lack of support for any or most advanced AGP features like sideband addressing or using main memory as texture memory via the GART driver. Early GPUs made no use of any of those features or they were purely optional and none of the voodoo cards used them either. Those cards used the AGP simply as a faster PCI slot.

Anything significantly more modern or AGP 3.0 (which made sideband addressing mandatory IIRC), or at least their drivers, will expect those features to be present and probably won't work when they don't. I suspect some compatibility issues with via chipsets (there is a reason sideband addressing was optional in earlier versions) comes from that as well.

Right.. so I shall see what cards I have that will work with the adapter. I'll start with the oldest and work my way up.

For reference, here is one of the really old style adapters.

ALBATRON was planning on making a PCI-E slot to AGP card adaptor. Not sure if it was ever actually released. I think I remember seeing one for sale or hearing about someone that actually had one.

Time for necroposting. I've tested some cards which worked on Intel TC430HX board:

All Voodoo AGP cards (obviously).
All S3 AGP cards based on original Virge design, including Trio3D/2x. No tested yet Savage 3D or Savage 4, so no idea if they'll work.
All original Rage Pro cards, including Rage Pro Turbo AGP.
Matrox Millenium II AGP cards.
Cirrus Logic Laguna 3D AGP aka CL-5465 (works very slow though).

Cards which did't worked:

3DLabs Permedia 2 AGP - can't boot OS with driver.
Nvidia TNT&TNT2 - can boot OS, but driver is not loaded.
Nvidia GeForce series - can't boot OS with driver.
ATI Rage LT Pro AGP and newer - can boot OS, but driver is not loaded.

Cards which potentially could work:

Nvidia Riva 128 & Riva 128 ZX
SIS 6326 series
Matrox G100

Overall this adapter works well with Intel chipsets, judging from Socket 7/Slot 1 era, but everything else is hit or miss.
