In addition, one of the key mechanisms has a broken plunger. Last, the little green paddle line power toggle power switch at the back appears to be broken.

I'm pretty sure Cherry is not still making these keyboards.
But, there were a HELL of a lot of them made over the
years. There were several key switch styles in use - really
cheap plunger that spreads the contacts apart when up, a
magnet and reed switch type, a Hall sensor type, and maybe a
capacitance type. The key switches should be able to be
replaced fairly easily. Special keycaps will be a harder
problem to solve.
