Re: Computerized billing ...
Many a happy summer in North Bay visiting my grandparents! Grandpa was in the RCAF and they ended up staying in NB when he retired.
Anyway, I'll never forget a school tour of CFS Moisie (Pinetree Line) in northern Quebec. The "Rabbit Ear" height-finder made a great impression as they activated it while we were in the dome (thinking about it now, just the antenna actuator - as I recall the wave-guides were well over a foot across and we would have been well and truly fried if they had switched on the transmitter!).
This was just before the first Quebec "Sovereignty Association" (Separation) bill in the early 80's. I asked the Base Commander what would happen if it was a Yes vote and I can remember his exact words:
"We have contingency plans to render this facility inoperable."
... always took that to mean they were going to blow the whole station up!
