I dug up this 80386 board with a Headland chip on it from my attick. After removing dust and inspecting it for any damage, I decied to give it a go and pluggied an AT power supply in it.
Lo and behold, fireworks arose from the power suplly connectors. Any chances of reparing the damage caused?
Did you put the plugs in the right place? Seems like they were inverted...
I stukc to the black to black-rule, so that's not it.
That's an awesome looking 386 motherboard.

I think it's just the capacitor next to the connector, looks like a tantalum cap which are prone to failure when they get this old. I'd suggest replacing all the caps on the board and trying it again.
If you are squeamish, don't prod the beach rubble.

Thanks for the info. I'll put it on the pile "to do" for now; it'll take a lot of time and effort to replace all those caps.
does anybody have more info on the board itself?
A couple of years ago, I got a 386/40 board which was a bit terribly damaged from the leaking battery. First time I powered it up, it worked fine. The second time happened the same thing. One of these capacitors exploded. It wouldn't post for a while. A couple of days later it started working again, and up to there seems to be no problem at all...
Wow! that's a pretty neat board.
But I noticed something.. one of the chips near the ISA slots has no sticker anymore, so it's probably erased by now.
