I have no clue how to use a slide rule. We have one around here somewhere. I know Dad knows how to use one, and my Grandfather would have been proficient with one. He got an industrial mechanical engineering degree from Pratt Institute in 1933.

Actually, once you understand a concept, it becomes vey easy. That's why I still can use the slide rule even though I learned it at high school in mid-sixties.

I'm sure I could figure it out, it just wasn't taught in my courses.

When I was in my first year of college, one of the guys on my dorm received an HP-35, which had just been introduced. My KE log log duplex decitrig slide rule suffered a major inferiority complex and crawled back into its case.

That was back when I was shooting with a Minolta SRT-101. I went to see the Royal Lipizzaners armed with Tri-X 400 ASA (no ISO then!) and push processed it at 1600. Nice and grainy......


I'd rather have a bottle in front of me than a frontal lobotomy.

You're most certainly allowed now! And more than allowed, you are welcomed, sought, and cherished!

The happiest of birthdays to you, youngster! May He ever hold you in the palm of His hand, and grant you joy and love.

It's interesting, even though I went to work for HP in the early '90s, and I remember the HP calculators from the "early days", I don't remember when, since I got out of high school in '69...were there any calculators back then, or am I just mixed up between slide rules and calculators...?

You're mixed up. The first pocket calculators (battery operated and fit in a large shirt pocket) appeared in 1972. All calculators before 1972 were desktop models

TI's first pocket calculator was the SR-10 calculator (1972), with four-functions plus exponent, square, square root, and reciprocal. TI's first scientific calculator was the SR-16 (1974), which had power, root, exponent, and log functions, but lacked trig functions. TI's first full-function scientific calculator was the TI-30 (1976). The TI-30 was possibly the most popular pocket calculator ever, probably because of its price—$24.95.

HP's first two pocket calculators (both 1972) were the HP-35 (full-function scientific) and the HP-80 (business).

I bought my HP-35 in 1972, about two months after it was released. I had it for about five years, whereupon it was stolen. I bought a TI-30 to replace it, and gave it away within a month. I quickly realized that, for me, RPN was the way to go. I've had HP calculators ever since.

Ah, well, it would have been the '80s, then -- I got into a tech college program to "catch up" with new technology and prepare for a career change...'course with such programs math is "built-in", so I guess that's where I got my exposure to calculators (I don't remember what my first one was)!

Here you be! A picture of a 42 year-old full-function scientific pocket calculator, the HP 35!

Just think! To be one of POTN's "older" photographers you don't even have to be as old as a calculator!
