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.
The Wyse terminal is a smart design choice. These older desktop / terminal systems have plenty of power to run a specialized software package, and they tend to last way longer than the manufacturer intended.
