HP-41CV awesome... I still use my HP-41CX to this very day... I have other RPN calculators for back up. RPN = reverse polish notation for those that don't know, the calculator has no "=" button. Extremely efficient for doing complex calculations like in engineering. Very few RPN calculators out there these days (SwissMicro is one) - once you understand and use this type of calculator you can't go back to using an =key calculator - only those that use RPN would understand this.

As for the carb vs FI debate, I have both so it doesn't matter which side of the fence I am on. I have to admit, after this winter, I was cursing the carbs trying to get the 74 started on a cold spring day. Crank and and ether, crank and ether, finally got it going. Yes I love the simplicity but carbs without chokes are a pain... The 73 with FI started without complaints...

Miss my HP48 GX - suddenly gave up the ghost a few years back. Stupid money for them on eBay. Cult status - just like 914s! (IMG:style_emoticons/default/laugh.gif)

I used to work for Agilent (formerly HP) & HP calculators were all the rage in college & grad school back in the "70s. One of mine was actually stolen off my desk when I worked at Ampex in the "80s. I still use my 15C, but I don't program it anymore.

i started with one of these in high school in 76.
couldn't afford a H P. unbelievably expensive in aus back then.
think this baby was an economy line by Texas Instruments.
was pretty good. started on RPN and can't even think with an equal sign calculator (IMG:style_emoticons/default/beer.gif)




when the Novus died sometime during university post grad days i had enough dosh to lash out on the HP. its still going strong. the enter button is a bit dodgy these days after 6 million miles of equations on the odo and i have to press it on the left hand side but she is still punching out the numbers and doing chain equations like no tomorrow.
great for checking dimension runs on shop drawings. (IMG:style_emoticons/default/smile.gif) (IMG:style_emoticons/default/smile.gif) (IMG:style_emoticons/default/smile.gif)

american engineering at its finest.

the 914 was probably designed using slide rulers?

[dgw]

OK you calculator nuts, I have an HP 11C. Anybody interested in it?

This discussion raises a couple of interesting questions:
1) Will those calculators survive an electromagnetic pulse event?
2) Will the D-jet ECU survive an electromagnetic pulse event?

I think my son’s Rolex can. It’s the Milgauss model. He was a physics major in college so he geeked out and bought it.

@dgw


The last year the HP-11c was sold, 1989, the price was $56.00... punching that into the US CPI inflation calculator gives that as $136 in 2023 dollars.

Ebay has them used from $100-200, not bad for holding its value after 34 years !!!

This series of calculator was amazing.. the batteries in Voyager series (10c, 11c, 12c, 15c,16c) last forever - over 10 years for my 12c. business calc. Impressive for not being solar powered with only 0.25 mW power consumption.

Not sure what's worse, being a calculator nerd or 914 nerd... but at least I'm in good company...

good question - especially if you live in taiwan.

possibly can survive when it comes to cars.
the body of the car itself provides a kind of faraday cage protection.
i believe small electronic devices are less vulnerable too.
ie phones.
it is thought that phones can survive it.
however the transmission towers and larger infrastructure circuitry etc probably don't so a moot point?
if a phone can survive it then a calculator probably can too.

however if you had your 914 plugged into a battery charger hooked up to main power grid it would definitely get fried.

i read something on this very topic a couple of years ago during late phase of covid lockdown when things were getting tense with CCP and australian exports were being soft blockaded and hit with tariffs by china for our signing of the new AUKUS deal with the USA and Japan over military security in the south china sea and pacific.
there was talk of how china would use a nuclear device to generate an EMP over taiwan and what it would mean. most military equipment is hardened against EMP.

I had a TI-66 in college in the mid 80’s.

It was worth every penny. I was allowed to use it during tests. I programmed in a very complex formula in it and past the test. Some students did it long hand on paper and flunked the test.

you forgot software nerd?

i am also one of those.
i run an off grid hp laptop that still goes (after 18 years) with autocad 2005 on it.
and windows hp. in my view the most highly evolved of the autocad programs by auto desk. after that they deliberately sabotageod the program with "upgrades" and "improvements" alongside their newly developed "3 D"software. i use my off grid laptop for anything i need to draw fast and with ease and then just bring files across to the connected equipment. there was a peak moment in some software. it doesn't wlways get better. a bit like cars.

nice bit of equipment. TI stuff was up there with HP.
but not RPN

us RPN guys are into the ENTER key. (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/biggrin.gif)
RPN is a real 70s thing that faded away as @Vitamin914 noted above.
but if you use one and get into it you just can't understand why the equal sign method won the day.

I'm guilty of that too.. I use an ancient 2D CAD package too. Mostly because I know all the two letter keyboard commands. Used to be called Generic CADD for DOS then evolved to Visual CADD in Windows. Back then was dirt cheap compared to AutoCad by an order of magnitude. Visual CADD still exists today and I can whip off a drawing in minutes compared the learning curve of anything else... rather drive the 914 than learn new software.

These were evil. Miss one and you were hunting for the missing bracket in a single line that you had to scroll through... miss two complete ones and you would have a horrific answer. One of the reasons RPN made it less error prone than algebraic entry.

Don't get me wrong TI had good machines but I just could not stand using the parentheses (bracket).

You did bring back an PTSD memory... had my then HP41C (the CX I got later) stuffed with formulas for first year electricity exam. To this day I still consider it retarded to have to memorize complicated equations - you always look them up the avoid the IIRC trap... Anyway, the exam announcement... open your exam and begin... Not a minute later I had three exam Procters surrounding my desk... asking about my calculator. Me ready to crap bricks being caught with what was in the machine... thankfully there is a three button start up that wipes the memory and displays "MEMORY LOST". Evidence gone. Still passed, thankfully, but it did rattle my nerves.

After that I wrote a program to simulate the memory lost display - never used it.
Remember if you are not cheating, you're not trying hard enough...

over here they just plain gave up on trying to police calculators in the university exams.
they figured you are smart enough to program one your smart enough to get the degree.
when i did my high school certificate the year before in 77 calcs were banned.
even the dumbo accountants type ones with equal signs.
you had to lay out your equations long hand line by line in the exam anyway.
i guess it was good. i can still do a lot of maths in my head which confounds young people when i got into big offices every now and then on red adair missions to fix up juvenile mistakes that could get my old mates with big offices in court.

the youngens can't believe i can do maths in my head.
or if start writing down equations they just get eyeballs that get very wide.
i often have answers before they finish pulling their iphones out and scrolling to find the caculator simulation. (IMG:style_emoticons/default/biggrin.gif)

one other thing from high school i fluked was learning to touch type.
they experimented on us in an early exercise in gender equality manipulation.
we had to do exchange with the girls who normally did typing (and cookery) they got to do woodwork and metal work. got taught to touch type perfectly. for one term.
can smash away at the keyboard on the auto cad program without taking my eyes off the screen. there were some bonuses to life as a teenager in the 70s. of course its all gotten right out of hand these days. the experiment has failed? (IMG:style_emoticons/default/beer.gif)
