It was difficult to find labs where I could make copies of my first tape; however, I found a place near LaGuardia Airport called Video Flight. They agreed to copy my tape. And while they were doing this I saw test patterns and other electronic images on the monitors that excited me. I spoke with the young engineers and decided to collaborate with them, returning to make a second tape of the electronic images. This manipulation of the test patterns became my second tape. The sound heard on the tape was from an oscilloscope, which I controlled, and through the sound I manipulated the images; later in the tape there is the sound of my own voice improvising as I reacted to the images. In 1973, Public Television in New York City, Channel 13, opened a new television lab and gave some artists access to it. The 55-minute black and white tape from 1966 described above was reprocessed in 1973 at Channel 13 using the Paik-Abe Video Synthesizer; thus the title 6673.
