[[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. | |||
