**Next week, Aldi is selling their cheap scientific calculator. I bought
one awhile ago and it is almost indentical to my Casio fx-82, which
normally sells for between $20.00 ~ $30.00.

** I have two calculators in regular use - a Radio Shack (Casio) EC-4012 and
a Casio fx-82SX. The EC-4012 was made in Japan and is 27 years old while
the fx-82 was made in China and is about 15 years old.

One sits near the PC and the other on my workbench.

The annoying thing is how keyboards differ SOOOO much - egs:

One has an X squared key with 2nd function of sq rt X - the other has the
reverse.

One has a "pi" key and the other uses the EXP for "pi".

One has a "y to the x " key and the other uses the X key 2nd function for "
x to the y ".

The heavily used 1/x function uses the 2nd function of "Min" on one and of
"EXP" on the other.

The only keys in the same places and doing the same jobs are the numerals 0
to 9 !!!


You woulda thunk Casio might have standardised the keyboards a bit better.

I used to have a HP 41C calculator, it stopped working many years ago and
was lost forever by the idiots at Wridgeways when I moved from OZ to Europe.
Don't do business with these crooks, they are unrepentant thieving bastards.

I have only ever used HP scientific calculators, 21/25?, 28 and now the
48G. The first two really wore out in under ten years <mitter, mutter>.

I wasn't impressed with that happening.

The 48g is only still going as it was/is hardly used.

My HP-41CV + extra memory + math function pack is sitting waiting for a
battery tab repair due to leaking cells......

That was my problem with my HP25 after five years. Self repaired/bodgy
and managed to get another five years out of it.

Does anybody actually use calculators any more? there are an abundance
of calculator apps for phones of every type and computers too. Even the
one bundled with Win 7 is pretty decent, even has a programmer mode.

**I can't speak for anyone else, but I use one almost daily. It's easier
than booting a computer. It's even easier than trying to find an
application. I can use one at the workbench, at the breakfast table, or
even on the sofa. Power consumption is minimal and for 4 Bucks, it
doesn't even warrant a second thought.

Still, I'm an old fashioned guy. I'm re-learning how to use my old Faber
Castell 2/83N slide rule. I even like the smell of the old girl.

Yes, far more convenient that find one of those and fiddling with the
keys or turning it on. Actually, my brain is just as fast as most
computer calculators.

Which shows you how useless they really are.

Only on one of your off days. :-S

I have used calculators since the HP35, after the slide-rule days. Have
for years had a HP200LX sitting on the desk, and used its calculator app
all the time. The biggest nuisance was I needed a different calculator
app to do hex/binary calcs. But now I use an app for the Android phone
which does all of the scientific stuff, in RPN, and hex/binary as well,
one touch to launch it on the phone, and its always with me. Yes you do
have to charge the battery every couple of days, but at least its only
one thing to carry around and keep track of.

HP-15C, all the time. Now over 30 years old.
Even have an HP-15C calculator on the i-device.

My computers are always on, just a case of clicking on the icon. If
there isn't a computer in reach, my android phone can do normal,
scientific, programming or financial calculations.

I've still got the Faber Castell 62/82 electronics slip stick, but it is
more of a sentimental attachment I haven't used it in years. I also have
a Casio scientific calculator that I bought in Japan back in 1982 and
have never found any better, but it hasn't been used in several years
either.

**I don't leave my computer on. It is not always within convenient reach
and I don't have a smart 'phone. I'm happy with my $4.00 calculator.

**Different strokes. I like having a calculator handy.

Aint RPN great, after using my 41CV for many years it took a decade before I
stopped looking for the enter key on other calculators.
I agree, I have to fumble around on any other calc, even for 1+1=2
stuff, and doing complex math is totally hopeless without RPN.
