I have a DVD I bought for $15 from electronix.com of test patterns. It has 6 patterns: Grey Staircase, Full Field NTSC Color Bar pattern, Split Field NTSC Color Bar pattern, Multiburst Bar Sweep from 0 to 4.5MHz, Cross Hatch Pattern, and 4 Rasters of White, Red, Blue, and Green. All test patterns also have audio test tones also that run in the background.

It doesn't have anything like the Indian Head Pattern or any old TV test patterns on it. But I do use it to calibrate both my b/w and color sets. It's something for now until I can obtain a real pattern generator.
