Sony pro moniton at Goodwill

[Eric H]

I just got back from GW, they have a Sony CVK-1900F sitting there for $29.95.
Near as I can Google it's a Professional Monitor circa 1982-84
It only had one RF type input on the back labeled VTR.

I'm guessing it was used as a security monitor somewhere, it has rack mounts on the side that slide into a slot.

I didn't get it of course, no room, probably has a million hours on it but it's supposed to be working.
