Pictured is a Yaesu FTM-100D (Japan Model), the HRI-200 interface, and a Wyse 3040 Thin Client running Windows 10.

I've found that these Wyse 3040 Thin Clients work nicely as a standalone Windows "appliance" for ham radio purposes. They're cheaper and run cooler than a Raspberry Pi and have more than enough power to run Wires-X or other ham software.

This specific model runs off of 12V/2A DC from the factory and uses the same size Yaesu DC barrel plug for power. It has 2GB RAM and a 16GB SSD, so I installed Windows 10 using the Tiny10 image. I have about 5GB of storage left over.

It works perfect for my use case.
