Just when you thought that you needed to upgrade your computer that is a couple of years old, the Grand Rapids Public School District shows off that they are still running their climate control system on Commodore Amiga computers that they purchased back in the 1980s. That's right, they have been running non-stop for probably about 30 years and have been going strong. Take that Intel!
The Amiga uses an unusual 1200-bit modem and a wireless radio signal to communicate with the 19 buildings. Each building reports temperature and the status of its heating and cooling systems. The computer can then toggle boilers, spin up fans, activate AC compressors, and so on.
