I bought a voodoo 2 for like 10 dollars knowing that it needed recaped, in unknown condition, and untested. I thought Id give it a shot on a recap. It also appears to have some bent legs on 2 of the chips that are touching but my initial insection didn't look like they were broken. . I am not a expert and what not. I wonder if I try to straited those legs so they are not touching and recap it if it can be saved.
The card looks like this one

The bent legs not sure if broken or not.

Why would you want to do that is beyond me.

because it has missing caps on it, and ones that look bad? 🤣

touching legs on the chips makes me not want to test it, unfortunately I don't have a microscope to try to fix those. I was considering investing in a stereo microscope and a rework station, for other reasons, maybe somone on vogons wants to try and fix the card for me. I knew most of this thats why I only paid 10 dollars for it but i didn't realize the dammage. Ill post pics.

I found syringe needles to be the best tool for straightening pins on QPF ICs, its sharp sloping tip lets you bend those pins as much as needed w/o deforming nearby pins. Some may suggest a sharp blade for this purpose, but it has to be super thin.

yeah a good exacto knife would work or a small needle as you said SSTV2. As far as the missing caps: probably knocked off by same thing that bent the pins being they are SMT and not solder thru type.

It doesn't always work like that. I just repaired a crappy TVGA8900 that had all the caps bent and broken. All for ¢25 and 30 minutes soldering. I'm no expert either.
Turning it on while you know it's missing parts is too risky in my book. Those 10u/16V caps cost maybe a grand total of ¢20. What's the hurry? Repairs take time. Checking continuity should be the first step to search for broken traces in the damaged areas. Skipping these and hooking the card up now could result in further damages.
It's just my opinion and it's your card and your time.

You can try the card without caps no problem (it will not cause damage) but make sure that all legs on the chips do not touch each other.

Many 3Dfx and Pentium III-S stuff.

I think if you just run DOS version of Mojo from a DOS boot it should not hurt the card missing the caps and should give you a report if the card is detected proper. If so then proceed with fixing the caps. I would be very wary of booting into Windows and running any major tests that will actually strain the gpu's or ram like Quake or TombRaider tests...just my opinion. Those caps are there for a reason 😀

Yes they are, and that reason is to protect signal integrity by smoothing ripple, not to prevent damage of any kind
