What surprises me is that somewhere there's an installation of Windows ME that "works".
Probably no USB devices, one of the very few video adapters which were reliable (cirrus most likely) and one of the very few reliable network cards (it's been too long - I forgot what worked on that front). Add a reboot job that whacks it once a day and you have something that may still do its job year after year after year as long as it is not connected anywhere outside its small local network.
