Back in the mid 90's I worked for a small company that installed and supported e911 and computer aided dispatch systems. They used dumb terminals for speed. One night when I was the on-call tech a small psap in a fire department station pages me for a dumb terminal. When I got there to replace it the dispatcher said smoke was coming out so he tossed it out the back door. He said he was temped to tone out the fire department

"Department #12345 respond to a fire call at...
your station"
