    Hey there all, I don't believe I've ever posted on this site before but I've used it as a source of information for a very long time. I just figured I'd show one of my projects that I'm currently working on as some of you might find it interesting :)

    First of all if you're not familiar with these boards.. They are basically two 3DFX Voodoo 2 chipsets in SLI on a single board. 4 boards = 8 Voodoo 2 chipsets that were used to achieve 4 tap rotated grid FSAA with no performance loss. These boards were used for military simulation and even NASA used them for certain configurations. (You can look up thedodgegarage to see more detailed information on these. Yes Gary Donovan I see you ;) )

    Around December of last year, I ended up snagging an extremely rare Quantum3D Obsidian 2 200SBi board on eBay that has a black PCB with the full-length heatsinks and 125MHz EDO from the later green PCB revision boards. The board also had the rare "546-0014-05" BIOS.. I've contacted every Quantum3D collector that I know personally and so far it's the only known 200SBi with this configuration in existence.

    Anyways, I ended up contacting the company that I bought the board from and of course the eBay operator was out sick... At that point, I called back every single day within minutes of the store opening to try and reach him. I eventually got in touch with the guy and asked if he had any more of the boards (In hopes that a full brick came in) and to my surprise, he had the other 3 boards with the bridge and all the hardware to mount them together. Unfortunately, the case and the rest of the system was recycled :c at least they had the common sense to not recycle the 200SBi's!!!!

    I promptly paid him over the phone (Trying to keep my cool and not scream with excitement) and the 3 boards + bridge + hardware, were then on their way to my house.

    At this point, I was freaking out like someone that had just won a 1million dollar lotto, as this was my dream to obtain a Mercury brick. I was useless at work that day from my excitement.

    When I received the 3 other 200SBi's, they all matched the first one however, they had 100MHz EDO instead of the 125MHz memory.. Interesting?

    The only logical explanation that I can come up with is that these boards were manufactured at the EXACT point where they were switching to the new green PCB models and some parts got mixed in the process. Which makes this a very unique brick! :)

    Of course, I had to assemble it because I couldn't hold in my excitement any longer.

    As I tested the boards the results were as follows.

    --125MHz EDO board (Board 1)--

    Perfect with no issues

    --100MHz EDO board (Board 2)--

    Perfect with no issues

    --100MHz EDO board (Board 3)--

    Texture errors

    --100MHz EDO board (Board 4)--

    Shows blue tinted image in 2D (Passthrough) perfect image in 3D



    For the year after acquiring these boards I was mostly focused on other retro PC projects and wanted to wait for the time to give my full effort into resurrecting this brick and making it 100% functional.

    That time is now.


    After finding out that the board with texture errors only had some loose pins on the QFP TMU on the far end of the board I started my re-work.

    In progress (Somewhere around 14-16 pins loose on the top right of the TMU. Some on the top pins and some on the right-hand side upper pins. Nothing some quality flux paste and a nice iron + microscope can't handle!

    And that leaves me here!!

    I'm currently troubleshooting the board with the blue image in 2D with a couple of my very intelligent retro hardware enthusiast friends. More updates to come!!

    Don't let Louis Rossman touch it looks like you did a good job fixing it.

    Seems like something erek and Red Falcon would be interested in. Very cool!

    Yeah, this is badass. I would be over the moon if I found three more boards to make a brick. Sooooo jelly.

    I was just a lot of luck and persistence. I typically search for Quantum3D hardware on eBay and other sources at least 6-10 times a day! I was very fortunate to find this board when I did... I got the brick very inexpensive as the company was clueless on the actual value.. Ha! :) Pays to know your S@#T ;)

    Good luck on getting the last board repaired! This is a great card, and I can tell you deserve this brick!

    Thank you very much! :) If I'm unable to figure out the blue 2D it shouldn't be an issue in brick form at all.. I'm not too worried about it.

    If only ;)

    Yeah it'll be extremely fun to see this brick up and running!! :)

    That's awesome! I think I have actually heard about this setup before, very cool to actually see some hardware.

    That is one of the sexiest pieces of equipment, setup, and repair job I have ever seen.
    Mad props to you for fixing and fully configuring all of it, not to mention finding and even knowing about it.

    You are truly [H]ard!!! (y)


    Thank you very much for mentioning us both, I greatly appreciate it!

    Thank you for the very kind words :) I really appreciate things like that. I'm honestly not the smartest guy at troubleshooting hardware faults but hey I am learning! :)

    I remember those cards from back in the day. I still have a Quantum Obsidian X-24 with the Medusa cable. It's basically a sandwiched variant of one of those Obsidian 2 200SBi boards.

    This brings back memories :)

    That's awesome!! I also myself have an X-24 with a homemade Medusa cable. :)

    My X-24 was my first ever form of SLI and it's my favorite single card I have ever had hands down. Bought it a few years ago and ever since I've been hooked on Quantum3D hardware!!

    Yeah, back in the day we used to fanboi on those cards in the 3dfx forums. They were "god-like" to us (the 200SBi boards that is).

    Hahahah that's awesome! Unfortunately I only learned about Quantum3D around 3 years ago.. Been following standard 3DFX stuff for a while now though :)

    I add no value on helping fix anything, but stuff like this is always amazing. Well done!

    Thank you very much :) In the photo it was before the soldering but I didn't drag across the pins like most people do because I was just trying to be as cautious as I could be with the pads. Doesn't look quite as amazing as the dragging techniques I've seen, but I would hate to screw up a pad on one of these boards haha!

    Based on the work you've done and the cards you have. I would say job well done!! Then look at my soldering and realize I have no clue what I'm doing!!! lol

    Welp the blue 2D passthrough was caused by a shorted CYBUS3384QC 10 Bit digital bus switch. Massive shout out to my good friends JJ Dasher and George Rudolf Mezzomo with helping me troubleshoot this board.. Now it's 100% perfect with a new chip! That means I now have 4 100% perfect Quantum3D Obsidian 2 200SBi's... Sooooooo stay tuned for the revival of the legendary Mercury brick!! 1f609.png ;) I'm beyond excited!!!!
