They'll never be shiny-shiny. If they're black, do it until they're clean. If they're super-dull, do it until they're not so dull anymore. But be careful.
Now that you've replaced your PS, feel the RAM chips. Are any of them hot? Like *really* hot? Might take a few seconds.
How about the lights on the ROM board, what are they doing?

Peale,
Do folks not use stuff like deoxit to clean contacts?

*shrug* depends on the application. I don't have any personally, and the pencil has worked really well for me. Plus it's cheap.

Shanman..
After looking at the schematic again, that jumper is supposed to be cut on the upright not on the cocktail. Mine came from a cocktail and it was cut....go figure!

It's actually hard to tell if any change occurs after using the pencil, but I spent about 20 minutes going over all the socketed chips except the RAM (since I'll be replacing it very soon anyway). I also did the connector pins.

None of them are hot.

Still all remain on.
Next I need to use the pencil on the ROM chips. Solder joints all look fine on the main board, including connector solder joints.
I still wonder if I have a bad clock - maybe the somewhat rusty crystal is bad? Unless I can find a reasonably priced scope soon, it will be hard to check this, so I might be running out of things I can try before shipping the boards off to Retro.
