Solid state computing with no moving parts actually has a very, very long shelf-life.
Does anyone know the name of a little screen like that? It's perfect for a project I want to do
Here's the back! 
Note that, in spite of appearances in the post's photo, it is a black-and-white TV.
Either the white balance is causing it, or the Samsung phone's smart camera is trying to be cute, but in real life it's greyscale even though the photo looks eerily close to the iconic C64 default colors.
That's a classic CRT portable television from probably the 1980's or 1990's. Brand is unclear.
I would actually say 90's since it seems like it has a coaxial input/output.
I'm not sure when C64's started having coaxial output as opposed to RF?
Commodore 64's were made to plug right into televisions so you didn't have to buy a specialized monitor.
Yes, it has "sorta" coaxial input with a small 3.5 mono jack adapter plug.
It is connected with a coaxial "antenna cable" which almost fits the C64's RF output and can be made to work if you bend it and shove some tinfoil in the gaps.
