Magnasync-Moviola Model TAC 502 Reader

Description

This is a Magnasync-Moviola Model TAC 502 Reader.
All I know about it is that it powers up and by briefly shorting together the brown and yellow wires on the attached cable,
the LED display goes crazy displaying a fascinating constantly changing array of non-sequential numbers.
That being said, I am selling for parts and
not
warranted for its original function.
This would be great for a science fiction set prop, as the display will keep going once started.
Dimensions are 19" wide x 1.75" high x 12.5" deep.
