Crispy fried chips

130801105805870978994I got an RS232 bit rate converter in for repair today. Tests indicated that it boots up fine but converts data in one direction only. Also the indicator lights do not light.
I opened up the case and ho-lee-cow! Looks like some hell of a voltage surge happened here. Maybe it got hit by lightning.

I’ve seen some charred messes before but I cannot believe this board still mostly works. It boots up and can send and receive data even though the CPU and RS232 chip are charred husks. Unbelievable!
