Back in the 70's I made my own circuit boards on the kitchen table so I

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.
