Were there any schematics for these cards ever available? Best I can do is look for the same size component.

no schematics AFAIK
what happens if you restore the L13 connection with a piece of wire?
It's part of the vga signal so nothing bad can happen
I would inspect the front ICs for detached/touching legs

Front ICs look pretty good, except maybe for some dust.

You were right. Looks like whole pad is gone (TMU chip). Will send it to someone with microscope.

Update to this thread: card was actually ok, I had a problem with LCD. All is well after pressing "autosetup" button. Could be a frequency glitch?
TMU pad is actually a factory "defect". There is a small blob of solder on the pin but it is connected to the copper pad.
Ferrite bead was replaced with this one: https://www.ebay.de/itm/274950610818
It's a 1206 package.

Soldering was done by a frend.

Hello!
I have non-working Dimond Monster 3D Voodoo. When running Unreal, gives an error that the card is not found. A visual inspection revealed the absence of two electrolytes. The rest of the components are in good condition, the legs of GPU are not bent.

I soldered the electrolytes, but it didn't help. The card is still not working.

Armed with a multitester, I went through all the components on the board. The inspection revealed some deviations of the resistances of the resistors from the nominal values. But the value of resistor R46, which shows megohms, but should be 0 ohms, turned out to be critical. Also, one of the resistors of the RP23 assembly shows 600 ohms instead of 47.

I replaced P46, also unsoldered and resoldered RP23. The resistance became normal, 47 ohms each in the assembly.

The card is detected in Windows 98, but Unreal and 3D Mark do not start.

Judging by the mojo data, there is still some problem. I didn't find any broken tracks, the radio components are fine. What else could it be?

Check for loose pins on the FBI, especially along the right edge and the top edge. Also check that the connections on the FBI RAM are good. My recent 0xdead voodoo card had a faulty memory chip on the FBI that was preventing the TMU from being recognised.

Could you boot straight to DOS, without booting Windows, running cmd prompt under Windows, or dropping from Windows to DOS, then run mojo again?

I have an STB 12MB that was reporting properly in Win98 and mojo (dropped from Win98 to dos). Swapped out with a PA2000 12MB, and this card shows in the cpl fine with all mem and tmu discovered, but dropping from Win98 to dos mojo shows the exact same as yours.

Swapped thr STB back in and it still shows up properly in Win98, but mojo now shows your errors.

Booting straight to dos, both cards report properly in mojo.
