I bought a control panel for a larger television video switcher (Grass Valley "Zodiac")
The top panel includes dozens of lighted pushbutton switches and lights displays and "T-bar" faders.
Underneath are a couple of power supply units (probably wired to be redundant for "hot-standby")
And some sort of a controller computer, complete with a 5-inch floppy drive(!)
Judging by the labeling on the buttons, it came out of KING-TV, channel 5 in Seattle (NBC)
Most likely still operational when replaced with newer HD, digital gear.
Not bad for $150 on Ebay. But I had to drive from Portland up to Seattle to pick it up (it wasn't worth shipping because it is so heavy). The traffic in Seattle is TERRIBLE! Bumper-to-bumper practically in EVERY direction! It took me 11 hours round trip from Hillsboro to Kenmore and back again. I must admit the gadget probably wasn't worth 11 hours of driving through heavy traffic.
