Does the fact that you are wanting to download a diagnostic disk mean 
that you have a ROM0 //c - i.e. the first model //c that doesn't have 
inbuilt diagnostics? You didn't mention if you'd tried to run the 
inbuilt diagnostics as mspangler described.

But to answer you question, you can download Apple II diagnostic disks 
from here:
ftp://ftp.apple.asimov.net/pub/apple_II/images/disk_utils/diagnostics

I'm not familiar with most of these files, but the file APTEST.DSK looks 
like a good candidate to try first.

To lift chips, you can use an IC puller (available from any electronics 
store), or gently prise up chips using a small jewelers screwdriver. 
Prise up one end a little, and then the other, alternating in small 
increments. Once the chip is raised sufficiently, gently but firmly push 
it back down. If you feel uncomfortable doing this, I suggest you ask 
someone who is more familiar, as you *can* easily break the legs off the 
IC if not done correctly. Also, it is important to discharge any static 
electricity in your body prior to touching any of the chips. Generally 
grounding yourself by touching the power supply is adequate, but an 
anti-static wrist strap is another option worth considering. Also 
remember to turn off and unplug the computer prior to doing anything!

Good luck. Let us know how you go.

Cheers,
Mike
