The market for such a device is probably too small.

By the time you add rpn, some more memory, nicer materials and some useful functions like numeric integration and an equation solver, I think you have the 33s. right?

Now you are adding cost and shrinking the market size. It is a no no. We want a BASIC RPN.

What I'd like is a very cheap and simple shirt pocket sized "4-banger" RPN model.

Yes..this is exactly i was talking about....a cheap/small calc..something around $10..just with RPN/algebraic entry...i think it is not a crazy idea and the cost for such feature must be quite cheap...

i really do not like the 33s..it is not a real shirt/cheap calculator


#27

As i said i really do not like the 33s..it is not a real shirt/cheap calculator and it do not have features VERY IMPOrTANT like unit conversion (i use it a lot)..i am thinking in something like this outstanding unit made by sharp:

...the bigger key can be used for a RPN entry.... all for less than $14...

this is a REAL shirt pocket calculator for just a few bucks...not these pieces of sh.....well..i prefer to say anything....(like 9s and 33s) made for hp right now...

Why do you need both RPN/algebraic entry in a basic 4 banger?

I just need RPN..but algebraic seems to be necessary for sucessful sales..RPN is not the preferred entry system for most people....but i think HP would have to support this entry system as its trade mark as something different to others...

Hi,

I don't know why 'HP' seems to be unable to produce a real low-cost RPN calc,

but there's some other company who took the ball:

To my knowledge the (currently) cheapest RPN calc is the AURORA FN-1000.

It looks and feels like a normal cheap financial calc,

but hey, unlike most other cheap calcs, it's a real RPN calc.

Actually it mimics the 12C, and comes with a very thick manual.

So if you aren't fixed to the big ENTER bar,

and don't need any trig functions built-in,

the AURORA may be the calc for you...

Either Staples or Frys should carry it.

Hi Raymond. According to this web site the Aurora FN1000 is no longer available:

I just ordered an Aurora FN 1000 from PCSound. $23.95+$7+ shipping (shipping a little rich) They showed 68 units in stock.

I really can't ask for more RPN calculator. HP would not be able to make money making them. I already have enough RPN calculators to go by. Those who don't have RPN calcs don't care about them.


#34

Yep. That is at the crux of the matter.

#35

But what I don't have is a low-cost RPN model that will fit comfortably in my shirt pocket. Or an RPN model that I'd feel comfortable letting a youngster carry around as a "first calculator".

James


#36

Youngsters of the future will have Borg-phone calculators with voice recognition interface.

Typical usage will be like ths, "borg, what is one-half times the quantity nine plus 63 + 1396 end quantity enter."

To which the calculator replies, "734. Hal may I help you further?"

Making a youngster using an RPN calc could be considered as child abuse.

I strongly disagree with that! I think that youngsters who haven't yet been indoctrinated into using algebraic calculators find RPN entry more intuitive.

The only problem is the question of whether RPN models will still be available when they've grown up.

Actually, the way I was taught arithmetic was to wright down 2 numbers, one on top of the other (a stack). Then you could add, subtract, multiply, or divide. The way I was taught arithmetic was analogous to RPN-wright down both numbers, then perform the operation.

Very good answer :-)

Anyway, children can adapt to diffrent concepts (as in this case RPN vs. algebraic logic) very easily, far better than grown-ups once the brain got "hardwired" due to long years of habituation.
Best thing is to let them use both types of calculators!
