A low cost DVD with all the patterns needed for linearity and convergence setups has been produced by Brenda Ann Dyer, and is available at the Early Television Foundation website:

I was looking for one of these as a cheaper alternative to a super expensive pattern generator! Thanks Steve. :)

That is a terrific service to the community. Many thanks. This will be a great thing for anyone who doesnt want to buy and restore a pattern generator just to set up and converge a set.

A few years ago I bought an avia disc. http://www.ovationmultimedia.com/avia.html It was expensive for a dvd, about $44.00 I think. I just wanted a pattern generator, I didn't really need all the home theatre stuff. Also, the patterns on avia dont run as long as you might like them to.
