There is an Amiga 2000 running day and night for 30 years with the responsibility to control nineteen schools’ air conditioning system in Grand Rapids, Michigan.
The system, written by a high school student back then, controls the start/stop of boilers, the start/stop of fans, pumps, monitors space temperatures, and few other monitoring activities. It uses a 1200-baud modem to communicate to a radio frequency system. The computer sends radio frequency messages to the schools, and they respond with status messages and so on.
The article, and the linked TV News video raise questions about why the computer wasn’t replaced before. The explanation was that the school district has other priorities, and despite of being old, it “just works”. Over the years they have to replace the mouse and the monitor, and on these occasions they did what we all do: eBay!
It is very exciting to see one of our beloved retro computers still being used in a production environment, running important tasks. Well done, Amiga!
