Mike,
Fortunately it is not a "resurrection" of the Eagle. It wasn't dead. So, I am guessing it was in better shape than "Lazarus".
However, there are a number of maintenance issues that need to be addressed. The most recent PO (Prior Owner) treated it ok, but was somewhat lacking on preventive maintenance and worrying about things that didn't work. He definitely did not abuse it; just kind of ignored some things.
Meanwhile, I do have a good photo of that schematic. However, the file is 2.7MB and I don't want to post a file that large to iRV2. If I reduce the size, it might lose some of the detail you may need.
Send me a reply to this PM with your email address and I will send it to you as the original JPG file.
Thanks for taking the time to read the discussion. I hope you are finding some useful things.
