I finally found the time to have one last go at fixing this A-Trend ATC-1762 VLB motherboard.

I started trying to get it working exactly one year ago, and got it done on the anniversary! It was a long repair that saw me having to replace the KBC socket and bodge a lot of traces because battery leakage completely ate them. Then I had to replace tantalum decoupling capacitors that decided to end their lives with a bang. Then the BIOS chip on the board turned out to be from another board entirely, so I replaced that. Finally, I had to invest into an oscilloscope to figure out my final keyboard related issues were due to a defective 7406 and replace it. All in all, it was an adventure, but I like a happy ending. It will never look as good as new, but this spaghetti mess is my only spare VLB board and a keeper 😀
