Does anyone have a user's manual for this board? 🤔

Do you know the brand? If you do try searching on this website: Mainboard.cz

There is a FTN-88 manual on file

The manufacturer mentioned in the manual is "Fountain" of Thailand. Not much else that I can find right now.

It makes non-stop 3 beeps 🙁

I suppose you have added some memory chips in there for testing etc. Are you sure all of them are in working order? Everything else in the system is tested known good?

I didn't touch anything. Here's the photo after cleaning:

Three beeps with an ami bios is likely to be a ram problem. Try to reseat the chips.
