I had the same issue with my scanner. I mentioned VirtualBox before. You can emulate a different PC and install an older version of Windows or some other OS with it. I installed XP (for older shogi software actually), and was able to install my scanner on that. You can then share files between you real PC and virtual PC, so I can still scan pictures and access them in Windows 7. Just an idea.
JEDIT: You could also just take a picture of the rules with a digital camera, assuming you can get a decent resolution.
