Hi all
 
Some time ago an old friend from 2CPU.com gave me a Quantum3D Obsidian2 X24 due to my knowledge of 3dfx and my passion for it
He is also a member @ EVGA Forums as JayVenturi

Even I asked him if he was really sure, thereby I advised him to sell it on ebay, since these can sell ot quite a bit, I also said I don't want to steal away a chance like that from him either.
He was like no man this card belongs in your home and in that old P3 you have there, so I was like okay send her up and I will elt you know if it has arrived.. or not :X

About 5 weeks later nothing had arrived yet, so I mailed JayVenturi and asked him when he shipped it, he was like hmm let me check with the postal services, about a week later he came back to me that it was at the customs I was like ahhhhh I beloved enemies lol he also laughed there

And about 6 weeks after that which was two days ago from today there was a big box from USA from G.Venturi on it I was like ahaaa this is it!!!
So I unpacked it and yaaaps it's the X24 alright! and that box is so enormous, dayum man!

Well I then unpacked it and started cleaning it and made some lovey photo's before I put in in Avenger M99, my P3/E 650Mhz test system

So here some pics which I did promise to make and yeah a review also, it's time to go back to 1998, the Voodoo2 age, the time when 3Dfx Interactive ruled the games market with their Glide API with about 97% of all games.. Meet the world's fastest and best siingle Voodoo2 ever made, all hail the Quantum3D Obsidian2 X24 PCI 24MB 384Bit EDO Rev.D 9822 / Fourth Final Revision D, Year 1998, Week 22.
Actually you can basically see the X24 as the GTX 690 of 1998, that kind of idea
 
Here the top view, you can clearly see that the slave V2 12MB is that half sized Daughter Board aka D-Board:

 
Rear view, shows some decals with a barcode and some warning, that long narrow one, the PCB date is 9822, meaning it's from Year 1998 & Week 22 An old Core Warrior of it's days

 
Here the headshot of this X24 Monster, as you can see it also has a S/Video & Composite TV-Outs on it, it supports PAL & NTSC, so you can go all ways with this thing as well.

 
Here the op of the box, it shows some battle scars aka weathering xD, but I don't mind, it's a gift from a good friend ya know, something I do plan on keeping for a long time

 
Here the rear view of the box, I made a clear show so you can read it all, I hope that will bring back lots of good memories for all you Quantum3D fans collectors and users!

 
Here a headshot I took of the box showing it's battle scars xD

 
The famous top banner of the box showing the beautiful Quantum3D Logo and the slofgan above the Obsidian2 logo: "Ultimate 3D Acceleration For PC games" Which was very true for it's time, and indeed this card is Single slot, more pics on that further on

 
The Feature Highlights tab on the side of the box, 384Bit EDO ram hah quite something for 1998, obviously 6x 64Bit EDO hehe smart marketing of Q3D, I do find their Details on their boxes extremely detailed, something I never saw on others.

 
Here the Specifications tab, and again very well detailed, always loved companies that really put everything in to detail, this is a very good example on how Specs should be written on VGA card boxes especially high end & enthusiast cards, such as this X24.

 
Well here it is then, this is what came with it, as you see no driver CD and 14 CD game pack or manual, no matter to me, I am happy for what it is, as finding these X24's with their original boxes isn't easy I was told. It was also the best performing Voodoo2 SLI Solution you could get as well, excluding Quantum3D's Obsidian2 200SBI's of course rofl which you can make in to Iron & Mercury sets..yeah the insanity Quantum3D knew exactly how to bring that!

 
Here showing how narrow the space is between the two PCB's and it's perfectly 1 slot wide too, Quantum3D really planned executed this idea out very well! 

 
Here a closeup also clearly showing how the two PCB's are connected together via it's two SLI connectors, an interesting approach but a very useful one also 

 
Here the main & slave PCB's taken apart also showing how the D-Board connectors to the main PCB vie them two long vertical SLI connectors and them three 4 pinned power connectors J3, J4 & J5 

 
Here the two PCB's seen from the other side 

 
Top view of both PCB's 

 
Rear view of both PCB's, in the four white holes go four plastic screws, they are good for the job too, just keep in mind when taking one of these gems apart, make sure you do that very securely, too much force and ware them screws very easily, patience plays a large role there 

 
Here an other nice orientation of the X24, showing it's D-Board and that cool Quantum3D slogan: The Affordable Reality Company hehe 
 
 
Here a different orientation of the X24, showing a weird 6 pinned connector just above the Xilinx chip, it's set to as J6, does anyone know what J6 was meant for?

Might be worth finding out 
 
Using the X24 is very pleasant, drivers are also dead stable, only what it is missing are feature settings which 3dfx did have afaik, the control panel doesn't offer that much besides the TV-Out section, that was very detailed, I also like them Quantum3D test logo's Although I am seeking some more Quantum3D tech demo's to test with the X24.

So here a video showing you the X24 running them Quantum3D logo tests in Glide without and with VSync enabled and showing some of the ATi rage 128 Ultra OpenGL & Direct3D modes

 
Here Unreal Tournament Game of the Year Edition 1999 in action on the X24:

 
I used my HD camera to record the footage of me playing the game, using fraps on these old PC's isn't doable, especially when recording and playing at the same time, thus I did it this way instead

Many thanks richj44 I do plan on running more glide games today too

Here some pics of the test system with the Quantum3D Obsidian2 X-24 :)

Quantum3D's 2D to 3D External Pass Through Cable, which goes from the Main VGA the 2D Card, that being the ATi Rage 128 Ultra AGP 32MB to the 3D add on card the Quantum3D Obsidian2 X24 and from there to the Monitor 

That is why NVIDIA bought the company
