The current company that owns the old model installed in your hospital and sells the new version, bought the company that bought the company that made the version you have and can’t update the firmware and code to work on a modern OS because all knowledgeable staff were lost in the buyouts.

The best they can do is sell you the new version that does the same thing your current working version does for $500,000.

Maybe they even have a new ecosystem that they want you to move to, because they don’t make support/subscription revenue with the current stand alone server that moves the image or telemetry results from the machine to the viewing workstations and records database.
