Calculators!!
(OP)
I just picked up an HP 35s, and I'm curious what kind of calculator's does everyone else use?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

I agree, I hated the hp33, the only reason I picked one up before was for the EIT.
RE: Calculators!!
Here's how to decode your HP calculator serial number:
Numbers are in the format YYWWC##### where
YY
Is the number of years since 1960.
WW
Is the week (roughly) in which the unit was made. YYWW is not always exact and sometimes may have gone weeks or months without changing.
C
Is the country code: A = America (USA), B = Brazil, G = Germany, J = Japan, S = Singapore, M = Malaysia or Indonesia.
#####
The serial number within the specified week and year. (This is not included in the Earliest Serial Numbers section because all are assumed to start at 0 or 1.)
Example: The museum's HP-94F is serial number 2622J00025 indicating that it is the 25th unit made in Japan in the 22nd week of 1986.

The 48GX will solve equations with multiple unknowns that I can't even do on my desktop. It's a shame that Carly Fiorina de-emphasized the HP calculator business. It made me happy when she was fired. I think there's a still a place for top quality HP class calculators.

I knew a 77 year old still practicing VERY experienced engineer who owned a HP that was so old all of the numbers were worn off. I thought it was so funny that I took a photo... I'll post if I can find it.
BUT, funny or not, I learnt my lesson. I own six of aforementioed Casio; three open (work desk, briefcase & home desk) plus one replacement for each.
I can completely see myself fifty years from now still using one of those six, long after the others have died, and giving some kid as yet unborn 'til 2025 the word-lashing of his/her/it's lifetime over a holographic projection of an undersized portal frame... My greatest aspiration is to be the old guy at the end of the hall. Unfortunately it's a position that take a lifetime to get in! ;0)

I dropped my hp 28s on the tile floor and all the keys on the left hand side popped off but that was OK because if I ever inadvertently touched any one of those keys I had to go get the manaual to get myself out of it. The right hand side is intact and functions perfectly.
The slide rules; well ever now and again I get one out and throw it up on my desk just to humble myself a little bit.

That was the cat's meow until I bought a new toy my senior year - IBM PC jr. Doubling the RAM to 128 KB and getting the second 360 KB, 5.25" floppy drive made me the envy of my soils class, setting up PC Calc (spreadsheet program) to do flow nets a breeze.

I had a 33s and literally threw it away a while back. Unbelievable piece of junk.
RE: Calculators!!
Tell me whats wrong with?

RE: Calculators!!
After less than a year, certain keys on my HP 33s lost their "springy" feel. This messed me up, because I type in numbers fairly quickly, and numbers were not registering on the screen.
This happened to both HP 33s that I owned.

If you decide to buy the HP, please consider me if you want to give away the Canon. Do you know if they still make calculators? I haven't seen one on the shelves in ages.
RE: Calculators!!
They do... And if they're available in New Zealand, I would think there's a darn good chance that they'll be in Aussie...

I must say that its been a long time since Ive seen a scientific canon calculator now that you mention it, plenty of canon desk calculators !
Ive had my canon for close to 20 years and its a work horse.
Would kind of miss it !
But I'll let you know if I replace it !
Thanks Jed
I see here in Australia the best price is about $105 (Aust)
about $84 US. Thanks for the link.
RE: Calculators!!
Interesting to know that Carly Fiorina is largely responsible for destroying such a great calculator. I may have to write her a strongly worded letter.
Oh, and the best part of this was HP48GX #2, I found it in a pawn shop for $4.25, I'm not kidding... I still feel like I should turn myself into the police.
RE: Calculators!!
I'm going to look for a Canon, as YS says they are available in NZ. Otherwise, another Casio will have to do.
If you have been using the Canon for 20 years, there will be an adjustment period if you decide to go to the HP Reverse Polish style. I used them a long time ago, but wouldn't go back now.
RE: Calculators!!
Sounds abit like me. My very first calculator was a HP 25 using reverse polish notation and if my memory serves me the very first programmable calculator, this is way back in 1975 in my first year of engineering at the University of Melbourne. We eng students really treated our calculators as calculators back then.
Your right don't really know if I'd like to go back to reverse Polish notation.
Let me no if you find a canon by the way.
Cheers!

I trust the Casio wasn't as painful as the Sharp one to sit on.

RE: Calculators!!
-it has an x^2 button without shifting,the 35s has an 'i' button instead, who uses that outside physics or EE?
-the 33s buttons have a nice hard click every time you push them, the 35s is almost squishy like a TI :^(
The 35s is much better looking though
RE: Calculators!!
Certainly not, the casio has rounded edges making it posterior friendly.

Although, my 42S screen is full of dust. Any ideas on how to clean this?

RE: Calculators!!
After college I bought the upgrades that came out but they were terrible (49G and 49G+), so I bought a 48G to use at work and keep another 48G as a spare.
That 48GX at home looks rough (beaten up in a booksack, then dropped from desks for years) but has never given a problem.
I recently converted a college intern that works for us to RPN. Once the light bulb went on, he said he'd never go back. He has a 50g that is quite nice and I'm actually considering one...

RE: Calculators!!
So wouldn't a cheaper scientific calculator like a sharp or casio about $30 be better value than a $110 HP 35S ?
What do you guys reckon?

I'm talking about something like
=concatenate(A2,"+",B2,"=",C2)
where A2 & B2 are values to be added and C2 has the formula =A2+B2
It's inelegant, to be sure.

Better would be to use MathCad.
