Default Alarm system transformer + power supply (would both go bad atonce?)

Back in the 70's I made my own circuit boards on the kitchen table so I
could build my own solid state alarm controls. Most of what was around
was the old reverse polarity on a pair going directly to a central
station like the police/fire department. ^_^



That depended on the type of equipment at the local CO. Touch Tone
phones had to be modified to work with the 1920s designed CO equipment
in my home town before the DTMF to pulse converter would work. They
really went whole hog in their conversion. Only 100 DTMF lines were made
available, out of 30,000 numbers.

We looked into manufacturing some alarm equipment, but the
manufacture's liability insurance was over $1,000,000 a year at that
time.

Well heck, what can I say, I grew up in Alabamastan. The most advanced
thing to come out of my province was this little space program thingy. ^_^


It didn't 'come out', it ESCAPED!!! ;-)

I spent a couple decades at Ft. Rucker, but the US Army claims it was
only nine months.



You aired up the tires on the choppers? ^_^



No, I maintained the WeatherVision system that provided weather data
to the pilot ready rooms, and delivered the base ETV programs to their
classrooms. We were only allowed 15 minutes downtime before they shut
down the airfields. Up to 17 of them. I also repaired a couple RADAR
systems when they were short on techs.

The only thing that was inflated on a chopper were the pilots. ;-)



Were there girl pilots flying choppers when you were there? You don't
want to dis your girlfriend if she pilots an Apache. ^_^
