Marlo and the Magic Movie Machine is a 1977-1980 children's television show originating from WFSB-TV in Hartford.
At night he builds, programs, and interacts with his Magic Movie Machine (Mert Koplin, voice) built using L. Dullo hardware.
The waveform from a real-time audio oscilloscope was displayed on the Magic Movie Machine's screen whenever it talked and it played short clips.
In earlier episodes, a split-flap display mounted on the console showed the code entered on the keypad.
Most of the time, Marlo used a small keypad consisting of two columns of buttons flanking a CRT, located in front of him when he was sitting at the console of the Magic Movie Machine.
