Vintage tech for displaying your Apple computer on a television screen.

From the ATV Research Inc website:

“In the mid '70s, the increased interest in microcomputers led the company into the RF video modulator business. Early home computer users did not like the high cost of monitors. They wanted an economical way to hook their computers directly into the RF input of their TV sets. A video input on TV receivers was not yet a standard feature. Likewise, computers were not available with built-in RF modulators. This obviously prompted ATV Research to quickly begin manufacturing both assembled and kit form units. These were primarily for use with the new Apple and other similar microcomputers. These early modulators were sold under the trade names "Pixe-Verter," "Micro-Verter," and "Apple-Verter." They sold by the hundreds almost immediately. With no more than 40 characters per line, the home TV worked perfectly okay. Besides, in those first years, it was not uncommon for the entire family to participate together in a computer game or with some color graphics program...and what better way to do this than to watch it on the big screen living room TV?”
