Since calculators had started to appear, I never did get formal
training in slide-rules. The LL scales still require me to glance at a

Whereas I started as a "no-good" Tech. It was the dropping of the code
requirement that encouraged me to try for the higher ratings. After all,
using a TS-570 just for 6m is rather limiting <G> [and even that was
difficult -- for a few months I had a mass PVC piping straddling a fence
supporting a pair of 6m HamSticks as a dipole... Until the apartment
manager complained.
Many moons ago, I could take Gregg shorthand at 100WPM <G> [but my
typing speed was only a slow 30WPM]
I regret that I never risked the $35 dollars when my college bookstore
was closing out the slide-rule display. They had the top Post bamboo
laminate rule at half price. At the time I'd bought an HP-25 calculator
[they phased out the HP brand a year or two later -- apparently RPN was too
confusing].
And, in a side comment, I once corrected a bookstore that had filed
Asimov's "Easy Introduction to the Slide Rule" under Science Fiction.
