+[[Linley Gumm]] says:
+<blockquote>
+The 140 color bar generator started out as a 067- test fixture intended to test vector scopes. I have some early front panels of same in my garage.
+[[Charlie Rhodes]], of course, fully intended to sell them as a product from the get go but needed to pretend to be doing a cal fixture to get permission to develop it.
