How could I forget about the power supply? I want to put a Seasonic SS-300FS Active PFC T3 with what I think is a date code for 2002 week 43. Should be sufficient. I think the original one had only a passive PFC.

I probably started thinking about rebuilding my first childhood computer before even taking it apart. I'm serious, this thing bugs me. It is time to finally rebuild it, not as a faithful recreation of the original, but as a pretty little box that contains what I consider as my ultimate Slot 1 system …

Fixing Missing legs is not very hard, i used a Dremel and sanded the Plastic until the carrier came out, then soldered wire to it and to the PCB. Cool, yeah when you know you can expose this frame, even an idiot with an angle grinder can fix this. I'm glad I got some good advice on this thread so I …

If possible, could you check whether your card is able to run games/tech demos with only TMU #0 present (might require to set TMU count to 1 via registry)? I think I need a break from soldering :D maybe my oscilloscope can help finding some clues. Would be great to see your Helios 3D fully alive as …

It works :) I resoldered TMU #1 and the RAM of TMU #0. First I was almost certain that TMU #0 had succumbed to the heat of my hot air gun: - mojo.exe only returned the dreadful 57005 TMUs (0xDEAD) - the clock TMU #0 -> FBI was only present on pin 40, not on pin 41 - the clock TMU #1 -> TMU #0 is …

TMU pin 184 is a stall signal. The naming of TMU0/1 is correct in the diagram. TMU pin 128/FBI pin 197, reset signal, from the PCI bus. TMU pin 128 seems to be supply voltage - did you mean 208? I still find it weird that the only other connection of that net seems to be pin 62 of the RAMDAC - …

Hi, how did you figure out which TMU is which (0/1), have you determined their locations by analyzing card or have you relied on some external source (datasheet/forum post)? Hi, the Voodoo 2 specifications by 3Dfx (rev. 1.16, found e.g. here just for reference) has a diagram on page 15 that shows …

Forgot to attach the draw.io file for the schematic. In the end I'm hoping for others to help improving it 😁 I'm not sure if I can claim any copyright on it, so I'm declaring it as Public Domain instead of CC-BY-4.0.

Okayyyy so first of all the scope picture in my last post is not ideal, I had my oscilloscope set to "realtime" instead of "repetitive" mode. With the repetitive mode it can make use of the full analog bandwidth (400 MHz). The passive probes are rated at 500 MHz. fbi_clkout_tmu1_16mhz.jpg That being …

Ahh this has helped a lot. I was pretty confused about the bus directions - now it all makes a bit more sense. Thanks!

I was looking for pinouts for the FBI and TMU to repair my Voodoo 2 (Creative CT6670) but couldn't find any. Right now I'm trying to figure out the connections between the chips to understand the architecture and know where to put my oscilloscope probe. If anyone has something, please let me know. …

The angle grinder might not have been the smartest option but it certainly was fun - thanks for sharing my enthusiasm and sorry to anyone who had to hold back their anger :) yeah next time I might use a file first. @auron you're right, the wire is too short to tape or glue it down. I'll have to …

I was hesitant to order some grinding and polishing bits for my dremel-like tool and I liked the idea of using a scalpel. Why use power tools when there's a good way to get it done without? Then I remembered that I have an angle grinder with a flap disk. angle1.JPG grind1.JPG grind2.JPG I guess I …

auron that's exactly what I was hoping to find after griding off some of the case, awesome, that gallery is very encouraging. I also like this flex cable approach. In my mind it's already fixed and working. I thought of using hot air to.. well.. I didn't think this through and was hoping for some …

Hi people, When I was in elementary school we had our first PC at home. It had a Pentium II 400 MHz and a Matrox video card (G400 I think), running Windows 98 SE. Now I remember that I wanted to play one particular game and it gave me one of these helpful error messages along the lines of "ahh so …
