TVs With Interactive DOS Applications?

So my hotel room in Edinburgh is tiny, but decent enough. I realized that it was missing things I’ve come to expect in a hotel room, such as an alarm clock, but was a bit surprised to see a note saying that I could schedule a wakeup call through the television. I’m fairly used to hotels having interactive TV systems using LodgeNet, which seems to be the standard interactive TV solution, but I don’t recall them offering a wakeup/alarm offering. So, I was a bit surprised when I turned on the little TV in the corner here and discovered what appears to be interactive TV using ancient DOS applications:

For whatever it’s worth, the wake up system actually works quite well. It turns on the TV and very, very gradually turns up the volume. It has helped me gradually wake up each day without any kind of shock to the system. I’m actually now thinking that something like this would be a lot nicer at home than the standard super-annoying alarm clock I use. DOS or no DOS, it’s pretty slick.
