Back in the early 1970s, I was the only student in my Associates Degree program who did NOT yet have an electronic calculator. I have to admit to the "entertainment factor", however, in watching all my classmates try to negotiate a seat near an electrical outlet in the classroom during tests. LCD displays had not yet been born and the old phosflorescent displays were hard on batteries. My slide-rule didn't care about batteries, of course :-)
Ahhhh the good old days.... I miss some - but not all - of them.
My K&E Cooke Radio (version of a Polyphase Duplex Decitrig) sits in its leather case on my desk. I have the original manuals as well. Bought it new from the K&E store in NYC and used while in USCG in ‘70’s and taught at the Electronics Training Center. Marvelous how the batteries are lifetime guaranteed, furthermore the battery “self resurrects” when the rule is passed along to a descendent. My 35 YO son is better with it than I am, but he prefers his circular rule.

I used a slide rule when taking the Advanced license test. Passed with flying colors. Still have it, and it still works.
During my satellite presentations, I will ask attendees to access their slide rules as we together derive satellite pass data manually, to graph each pass on equatorial graph paper …
“What - no one has a slide rule?” I will playfully chide them. “Didn’t the club president tell you all to have him for the presentation?”
Well, the Puget Sound Repeater Group just floored me: EIGHT SLIDE RULES were in the audience (three from one person, including a circular one and I recognized another as a Pickett Vector Model 300 - in its original leather case)!
A wonderful club. Sixty-two total years of supporting their region. Multiple daily nets that are well-attended (I know - I monitored ‘em via Echolink for a couple days). ARRL Special Service Club …
And very exciting for them: a 89-degree elevation pass of the ISS this evening during their 9PM Net!
I lost count … I think this was the 144th or 145th show presented. It is not getting old … as long as clubs want to know how to work the "easy” satellites, AMSAT will get the information to them!
