Thanks to Dan Edwards of Pact-One for telling me about this.
NUC stands for Next Unit of Computing. It is an ultra-small fully functional computer that can be used in a dental office. The unit is 4” x 4” x 2”. It can be hidden in a drawer or mounted on the back of a monitor using standard VESA connections.
It has a USB 3.0 slot that can be connected to a hub for multiple inputs like digital radiography or cameras. It also has multiple display capacity to power two displays using HDMI output.
