Newbie with a fried 1200.

And the psu is in good working order?

I have no idea. I don't know how to find out either. Is that something a lay man can test with rudimentary household tools? It would be nice to determine if the psu is still kicking...

You need a cheap voltage multimeter gadget and know which pins to test, which i sadly dont have the expertize to help you with. Here is a picture of one of these gadgets, which should not cost more than like $15 at max: http://shopping.redorbit.com/edmunds/images/cce711f0c2e19fc3c917f60401e91fda.jpg

The easist way would be if you knew someone with a working psu that you can test with your amiga.
