Nah - that's nothing.
When I worked for IBM as an engineer back in the early 80's I had a 3270 dumb terminal arrive for service that had come in from Mt Isa. It was still working perfectly but had come in for preventative maintenance with a bunch of other stuff.
When opened, we had a layer of bauxite dust at least an inch thick over the entire insides. Once removed by judicious cleaning processes it never worked again.....
