Vintage Digital Comparator 1715 Electro Scientific Industries powers on UNTESTED

Description

Vintage Digital Comparator 1715 Electro Scientific Industries powers on but untested.
Look over pics. Item powers on lights up but is sold untested as is. Does not come with a power cord. I have 2 of these. I used the cord from the other to see if this turns on. Pics of inside. Looks like it was repaired at one point. You can see the solder job. I will set up another listing for the other but we could work out a package deal if someone wants both. Any questions just ask.
