The designer of the TV Typewriter, Don Lancaster, developed a low cost video display for the KIM-1. The add-on board would display up to 4000 characters on a TV or monitor. A typical configuration would be 16 lines of 32 upper case only characters. The board had only 10 low cost ICs and used the KIM's memory for the screen storage.
The TVT-6 project appeared on the cover on Popular Electronics in July 1977. The complete kit could be ordered from PAiA Electronics for 34.95 US$.
Don expanded this design to do color and simple graphics in The Cheap Video Cookbook.

Famous quotes containing the words display and/or video:
“Life is extraordinarily suave and sweet with certain natural, witty, affectionate people who have unusual distinction and are capable of every vice, but who make a display of none in public and about whom no one can affirm they have a single one. There is something supple and secret about them. Besides, their perversity gives spice to their most innocent occupations, such as taking a walk in the garden at night.”
—Marcel Proust (18711922)
“We attempt to remember our collective American childhood, the way it was, but what we often remember is a combination of real past, pieces reshaped by bitterness and love, and, of course, the video pastthe portrayals of family life on such television programs as Leave it to Beaver and Father Knows Best and all the rest.”
—Richard Louv (20th century)
