An oldish hard drive, loaded (it says) with CYGWIN. It has a USB connection and another which I think powers it. A few screws missing, but it's not falling apart! Weighs nearly 2 lb. I've not managed to power it up so don't know the capacity. (Wiki says Cygwin is a collection of open source tools that allows Unix or Linux applications to be compiled and run on a Microsoft Windows operating system (OS) from within a Linux-like interface. Cygwin offers users a Linux-like experience in a Windows environment.)
