Magnasync-Moviola Model TAC 501/502 Generator/Reader

Description

This is a Magnasync-Moviola Model TAC 501/502 Generator/Reader.
All I know about it is that it powers up and by pushing various buttons, the
LED display works, generally starting with an odd number and counting up by two's but not always.
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 counting once started.
Dimensions are 19" wide x 1.75" high x 12.5" deep.
See a similar unit I am selling.
