Recently, I came into possession of an early 1980's-era vintage computer from Wang Laboratories. It belonged to my grandfather and was found in his attic along with a monitor and keyboard from the same company. Unfortunately, after getting home with the equipment, I discovered the computer is not working properly.

I don't have any of the documentation for the computer (assuming there was any to begin with), and I know next to nothing about troubleshooting vintage computers. I also having trouble finding any resources (technicians, learning materials, etc.) that could help troubleshoot the issue(s) I'm having. I've always been particularly interested in vintage computers, and now that I have one, I'd like to be able to get it to work.

What are you recommendations? Are there any wikis, books or otherwise for learning about vintage computers?
