Hi, retro hardware fellas. This is what I got today from ebay as "Condition: For parts or not working - Not tested":
The damaged capacitor is marked in red rectangle. I think this damaged electrolytic capacitor is just a decoupling cap and it is not a serious damage. All other electronic components on the PCB seems to be OK after a visual inspection with magnifying glass.
I decided to use "mojo.exe" tool for quick test of the card under DOS and since I have no experience with this tool, I'm asking for help to determine if the output is OK or might be some potential problems.
Here is the output after these commands
"set SST_INITDEBUG=1
set SST_DEBUGDAC=1
set SST_INITDEBUG_FILE=3dfxsst1.log
mojo.exe":

Why the log ends with "Returning with status 1..."? Shouldn't it be "Returning with status 0..."? And also: "sst1InitRegisters(): exiting with status 1..."?
And here is the output after these commands
"set SST_INITDEBUG=1

The following lines bother me here:
"DPMI: GetDeviceID returns NULL!!!
DPMI: Couldn't get VXDLDR entry point"
I'm asking for an opinions if this card has some more potential hardware issues, based on these log-files from "mojo.exe". I'm sorry, but right now I can't install Win 98 and test it with some Glide game.
EDIT: As usual, I ask myself and answer myself, finding sources with some information.
On BuB's YT channel in one of the recent 3dfx Voodoo repair videos there is part with shown mojo-output like one of mine with "DPMI: GetDeviceID returns NULL!!! DPMI: Couldn't get VXDLDR entry point". It seems to be some initialization of the "mojo.exe" utility that is related to Windows 9x, not the videocard. So that's clear to me now that at least this is no problem.
