I refurbish medical devices in California. The customer can either talk to sales or talk to me. Medical devices are a computer-controlled apparatus, and the computer. I can fix the computer without affecting the device's calibration. Devices don't break often, but their controlling computers do.

The oldest devices I serviced run on Windows 3.1 and still work fine. There's a touchscreen mono CRT that runs on some custom build of Windows 3.1 in daily use at that office. I use Windows 98 daily.
