Greg,
You're definitely one up on me.
I tried to work out how to use a slide rule, it made no sense at all.
This was obviously back before we had things like the Internet to learn such things and I'd never really given it a second thought since.
Wasn't the slide rule the "be-all and have all" for the young engineers of the day, often worn as a fashion statement?
I can't think who would do that, but there you go, I asked the question.
John,
One thing needs to be said here, New Zealand back then, was a closed-minded place, we didn't get calculators in schools until 1987?, if you wanted to buy one off the shelf, they were a luxury item and taxed as one.
