I have never had a problem getting hold of Dan. Why not call him:

Ph# (541) 782-4404 / (cell phone) (541) 914-2656

He does have a PDF catalog, although it has some hard to read parts. Here's the link:

I don't know exactly what you mean by the second item.

As to the computer purchase, if you purchased with a credit card you should contact the credit card company. Most credit cards now come with buyer protection that may give you up to a six month satisfaction guarantee. Some states also have consumer protection laws that may give you the right to what you want.
