An Old Amiga Commodore Operates Heating and Air Conditioning Systems for 19 Public Educational Institutions
In the heart of Michigan, the Grand Rapids Public Schools (GRPS) has been relying on a piece of technology that harks back to the 1980s - the Commodore Amiga. This unique system, which has been in continuous operation for over a quarter century, controls the heating and air conditioning systems in 19 schools across the city.
The Commodore Amiga, purchased with funds from an energy bond in the 1980s, operates on short-wave radio frequencies. It sends out commands over these frequencies to control the temperature in the schools, replacing a much larger computer that was approximately the size of a refrigerator.
However, the Commodore Amiga's method of operation, while innovative for its time, presents some challenges. The radio frequencies it uses are also used by maintenance workers' walkie-talkies, causing potential interference. Its replacement, should a $175 million bond proposal pass in November, would not replicate this method.
The current state of the Commodore Amiga, being 30 years old, is sub-optimal. Its parts, particularly a 1200-bit modem, are difficult to find. If the bond proposal passes, the cost of replacing the Commodore Amiga and associated system would be approximately $2 million.
Should the Commodore Amiga fail, the systems at the affected schools would need to be controlled manually. Tim Hopkins, GRPS Maintenance Supervisor, emphasised the need for an upgrade, stating, "We can't afford to risk having our schools without proper heating and cooling systems."
The Commodore Amiga's continued operation is uncertain. While it is still functioning, its continued operation is not guaranteed. The community awaits the outcome of the bond proposal, hoping for a much-needed upgrade that will ensure the comfort of students and staff in the schools of Grand Rapids.
