Does anyone have or could make an inventory of the values of electrolytic capacitors on this board?
Most of those missing Electrolytics should be same as most any other TX chipset board since they are just filters on the power traces, except the VRM ones those would be specific to that board....
added: for reference here is a semi-functioning board with good pictures: https://www.ebay.com/itm/183802191107.
Appears the three large missing by VRM are same as the one you still have, on my TX board the small ones by the PSU connector are 10u 25v, the ones near the cache are 470u 6.3v, the two near IDE are 270u 16v
not that your board is same as mine but just an observation.

Thank you for your response.
I have a few doubts, I marked the points with numbers.
1. It seems to me that this capacitor is lower than the middle three which are 1000uF 16V which may suggest its smaller capacity.
2. It seems to me that the capacitors close to the cache cannot be 470uF because a capacitor with this capacity is in the place I marked 4. One of them is probably a bit larger.
3. I am not sure about this.
I checked all the motherboards I had that could be similar, unfortunately the only ones I have are VX chipset, but the layout of the components did not solve the above dilemmas.
At most, I will put up for sale in its current state.
