After a long time I decided to do something with a soldering iron, because I love doing with this equipment, so I put my attention to 286 board from Japan. I was cleaning battery leakage, it was going well, I was able to remove blue-ish crystals with vinegar and small knife, soldered out the keyboard BIOS because rotten traces went under it and I wasn't able to see where it goes. It went to one pin that was eaten out, so I meaured the traces, repaired the pin with wire which came from a capacitor and soldered it back in place. That was going well. But I decided to do second chip which had some corrosion on it as well. It was quite late, as the matter of fact I was sorting through my PSU stash since 9am, now it is 11:27 pm and I desperately need to go to bed. That was the biggest reason why I screwed up.
OK, what happened?
When I was desoldering badly placed chip between two ISA slots, I managed to crack the chip in half. The chip is completely ruined, it is cracked in the middle and pins fell out. So, you are guessing correct, where I can find replacement?
At the beginning it looked like this
I cleaned the board and desoldered keyboard BIOS chip
Then this happened,
So I ended here.
And I don't know who is the maker of this chip, what is it's purpose and where to find replacement. I feel like an idiot and moron now, but it happened and it can't be reversed. And I can't even find anything about the board, because it only has label saying 103FS with japanese symbols stamped around.
I haven't ever done so much retro tinkering stuff in one day, I need to order some caps, but shipping is pricey so I have to order as much stuff as possible, so I went through 35 PSUs, opened every single one, wrote down bad caps to order, cleaned and oiled fans, then I checked bad caps on stored mainboards I have (around 15) and started going through towers, but I didn't have time so I went home and continued there with this board. But since I am not coffee drinker, I am now so tired that I am losing track what I am writing about and even forgot how to english, so I gotta put everything down and go sleep before I do something what would piss me off more.
