Sounds like R22 followed in the footsteps of Halon (new production banned in 1994). I was always a little worried about a Halon drop when I worked at NORAD administering the WWMCCS warplan machines. Lots of old servers in that HUGE room, and at least half of the subfloor was stuffed full of cables that may have been from older versions that they left in place. I was there in the early 90s.

My jaw was hanging the whole time that I walked around the facility in the late 70s.
