Archer Video Selector Cat No. 15-1261

Description

Up for auction is a
Radio Shack Tandy Archer Video
Selector Switch 15-1261
TV VTR Coaxial preowned and
I am assuming used, condition
Picked this up at an estate last year .
Box has some wear
Do not have the slight-est idea how something like works or what cords ( coaxial ?) they are referring to..
No cords or anything with this - what you                          see is what you get.
But does have paperwork in box.
Thanks for looking -   Andre`
