> 5-10 years is not unreasonable expected support I think.
A couple of years ago, I helped a small business with an embroidery machine that runs Windows 98. Its physical computer died, and the owner could not find the spare parts. Fortunately, it used a parallel port to control the embroidery hardware, so it was easy to move to a VM with a USB parallel port adapter.
That was very lucky then. USB parallel ports adapters are only intended to work with printers. They fail with any hardware that does custom signalling over the parallel port.
