After some 12V seems to have made its way into the D1 line and fried this part, I am looking for a replacement VT82C481 (QFP) for a board similar to the FIC 486-VC-HD, etc:

I've tried inquries with many of the better known suspects (utsource and a lot of brokers) but didn't get any offer so far.

If someone knew of a good source, or might have a broken-beyond-all-repair mainboard and could ship in Europe, that might also be an option to revive this one.

This of course isn't any sought-after board at all, but I just don't like another 486 board to be on its final journey, if it could be helped.
