I'm collecting old mining equipments for cheap prices. It's just for fun, I don't turn them on. Anybody with a sane mind won't buy them for real mining for profit.

They are still good learning tools to. For someone wanting to learn about mining with little money you can grab one of these.
To be honest I'm surprised the value they still hold. It seems collectors and those wanting to learn are there, and there is a market.
