Wow, talk about a blast from the past. I haven't seen those since the late 90's. My cable co. began phasing out those things in 2000 in favor of digital boxes. I thought they were fascinating.

I'm pretty sure the local office would have to make a call to corporate to figure out what to do with it first anyway, hahah.

My grandparents had one of these for the old UHF/VHF set in the early 90's or earlier:
