Turned on my Asteroids Deluxe to start looking into a 60 cycle hum problem. Was turning the volume pot (very crackly. . . dirty I assume) and POP!! Screen went black and something inside started smoking. Unplugged it and went to get a flashlight. By the time I got the flashlight I couldn't tell where the smoke was coming from.

I'll have to try to figure out what happened soon. Any pointers are appreciated.
 
Was the smoke hi or low? Most likely a fuse.

Start with the basics:

1) Test all fuses on the power brick and then the monitor
2) Look for burnt parts
3) Unplug monitor and edge connector and test the voltage testpoints (5V and 10V) on the power supply board

... steps to follow depending on results
 
Wad the pop come through the speakers or from inside the cab?

Does the game play blind?
If the sound came from inside the cab and it plays blind. check the flyback...
