12C for 11C and 15C fanatics



#2

I'm just wondering if their are much 11C and 15C users making use in day to day situations of the still available 12C (voyager series)? (because they like the RPN, the good placed large 'enter' key, programmable, ...)


#3

For day-to-day use (I'm going back to college to become a middle school math teacher), I just use a $2 4-function calculator. When I want to play around with number theory, though, I use my 12c and also my 11c and 16c sometimes. For serious number theory stuff, I use Mathematica on the PC.

#4

In the 1980's and early 1990's -- before desktop PC's became the standard -- my employer provided HP calculators for their engineers' use. Many got Voyagers (15C's primarily, but also a few 10C's, 11C's, and 16C's). 28C/S, 41CV, and 48SX were also distributed, as well as 20S and 32SII's later (sometimes as replacements).

These calc's are still in regular use (some looking rather rough). Other engineers, who came along after the issued-calculator program ended, use their personal HP calc's at work.

I've got a 12C, a 17BII and a 41CX in my drawer. I usually take the first I catch, opr depending on my mood.

#6

The only calc I use right now is my 15C. Carry it in my bag all the time.

Hi Michel. I use both a 12c and a 33s at work. I prefer the landscape layout and display of the 12c over that of the 33s and therefore end up using the 12c quite a bit for simple arithmetic as well as for the occasional financial calculation. The 33s is there for more scientific inquiries. Since both the 12c and 33s are still being sold I have less apprehension about leaving them lying around on my desk. This strategy allows me to leave my more valuable HP museum pieces at home.

I hope that this helps.

Regards,

John

Coming from a 19C, the 41C system, today I use mostly a 32SII for daily duty. For data collection I have a 48SX at the office and mirrored software/data thru PC at home on a (few) 48GX.

The 12C is only used for its great financial interface. I carry the 15C instead of the taller 32SII when I'm "white collar" dressed: The voyagers are heavyer, but they fit better into a white shirt's pocket.

All the other calculators are for math and collector fun (thank to all the community here!)


#9

Wanted to return to use good old calcs in business and took my 11C or my 42S to work several times (always "white collar"). Well, it turned out they were competing with my PDA to occupy the ONE shirt pocket. I have MathU on my PDA plus my calendar plus some other useful stuff. So guess which won?

@Valentino: I tried to verify your result. So far, I did not find any voyager being heavier than a pioneer. What did you compare?


#10

@Walter B: Maybe I wasn't exact enough in my spelling.
I meant that a Voyager feels more like a "brick" in a fine shirt, then the Pioneer formfactor. IMHO.
But it looks metallic and it is definitly an eye catcher. More then the plastic only look of a Pioneer.

Hi!

I used to use 17BII+ in office and studies. Now, I am using 12C.

Due to the exam requirement, I just bought a second hand 12C at eBAY and started to familiarize it by using the 12C in both work and studies. My 12C is 23 years old and it's still working fine!! (Thanks to the previous owner to keep the calculator in good condition)

Regards,
Walter

Until a year a go, I never used the 12c, but had been a long-time user of the 11c.

I have not found anything good about the 12c for daily use. It is missing one of the most basic and useful features: a backspace. And its programming method is useless if you are used to a better system like the 11c. And no trig. So, no, I have not found any "general use" for it. (Though its financial stuff is handy).

On the other hand, I like the 17bii quite a lot. Though once I traded for a 27s I was really happy.

The 11c and 32sii are so much more fund and easy to use than the 12c, that I just don't find any reason to use the 12c unless I want to do a financial calc--and then I would rather use the 27s or 17bii anyway.

I sound very critical? And I am a died in the wool classic HP fan? How is this possible?!

Because I had never been exposed to the 12c until after I had been exposed to newer and better machines. (I also find the 41c a bit archaic.......though very cool nonetheless).

regards,

Bill


#13

I use the 49g+ only



I'm willing to sell all other calculators away:



16C,25,28S,32S,32SII,41CX,42S,48SX,49G,71B,75C;+modules & digital cassette drive & other goodies; I need the money!

@VPN: really? hehehe...

I do NOT know you personally, but I - and others - know you virtually best here in this site, so: If I would believe your ad, I would ask you the sum you want for your jewels.

But I don't ;-)

#15

You better believe that I'm selling *every* old=discontinued calc that I own:

including 71B 75C etc...

9999 Sterling Pounds

#17

9999 Pounds?
Did I ever mention I'm a millionair? I don't remember...


#18

You don't remember?

Ah-haa! :-D

But you already bought them from me and you still own me one million

...I like the dadaistic touch of this forum. Really, folks!
At least of some people here...

I did it just a year ago. I lost my beloved 11C some time ago and got a 12C to partially substitute it. The 12C is a preety good machine, but unfortunately it lacks some important features the 11C had. Later on, I got myself a 32SII, and kissed the 12C goodbye.


#21

@Bernardo: You too found the 32SII for daily use? Congratulations. I'm an afficionado too!


#22

@Valentino: Yes, I find the HP32SII just great for daily use; it's got a lot of useful functions, actually more than the beloved 11C and 15C, it's really FAST, its menu system is not cumbersome, it's very thin and light, and its display is large and clear. I only miss the panorama design.

Actually, as a 41CV ownwer and fan, I must confess that sometimes I run some routines on the 32SII and use these partial results to feed larger programs to run on the 41CV. This is because, as I said, the 32SII runs faster, and works with 12 significant digits. Also, the SOLVE program of the 32SII is superior to that of the 41CV's MATH1 module.

I agree with all of the above; I use one also at work.

Also agreed, but I should mention that the machine-coded SOLVE and INTEGRATE routines on the HP-41 Advantage Pac module are better than those on the Math Pac module. The two Advantage Pac routines are closely based on the ones in the 15C and 34C, which in turn were enhanced for the 32SII.

Advantage ROM's disadvantage is that the financial routines (IRR) do not use the ML SOLVE routine

@Karl: thanks for the tip on the Advantadge module; I'll get myself one. = )
