I think you need the TI-36X II:

<http://education.ti.com/downloads/guidebooks/scientific/36xii/36xii-eng.pdf>

Looking for recommendations re. a handheld calculator that will 
handle 16-bit binary calculations, conversions, logical operations 
(including 1's and 2's complement) and hex, decimal (of course).

(Does anybody use octal any more? Seems many calculators have it...)

Thanks,
Dave

I'd love to find one too.  I use my HP16 just infrequently enough for  
the RPN to be a pain.

Any Palm PDA will run the RPN calculator program. It works very like the HP 
calculators, and should do most of what you want. I use it a lot.

That's going to be a tough one (maybe).  It would have to be a newer 
calculator than the ones I have!

My TI-36X only does 10 bits in binary. It will do the required number of 
bits in hex, but won't convert any hex number of more than 10 bits to 
binary.

The last time I used octal was with a PDP-11/20 over 30 years ago.

Thanks!  I haven't been keeping up and didn't know they had a Mark II.

I use "Easy Calc" for my Palm PDA.  It does 90% of what you are talking
about.  But it does not handle complements.  It's shareware.

I have a solar powered Casio at home that I got 20+ years ago. I
don't recall the model # but it handles BIN, OCT, DEC and HEX
4-function ops and basic logic functions on up to 32-bit values.

It paid for it's self a long time ago and the batteries still work!

Bruce

I have the same Casio (it sounds like) and it too still works!   Steve

If you can get away with using your computer, how about the calculator 
function built into Windows XP? It appears to do all you ask to 64 bits 
except for the complements which are easy enough to do yourself.

Please look at it and report the model #. I'm interested. You're sure 
it does *binary* to 32 bits? And displays it? (Most new calculators 
won't display more than 16 digits, so I'm suspicious...)

Thanks,
Dave

Ok, I got home and tracked it down. It's a Casio model CM-100 that I 
got for free, in 1986, as a promo for buying a graphing calculator. 
I stuck it into the scanner and posted the resulting  pic in the photo
section of the Yahoo web site.

The COMP button puts the unit into normal floating point mode and any
of the BIN - HEX buttons switches it to integer operation. And yes,
the A-F keys expand the numeric pad to 16 digits in integer mode. I'm
sure this model has been out of production for a long time but, if you
can find a working one, it's worth it. Not a high power unit but, like
I said, the batteries still work!

Check the NOT button.  What do you think it does? ;)

I agree, the CM-100 is the one to have. I've used mine daily for ~15 
years & it still works great. Amongst the many nice features is its 
ability to show the status of Carry and Overflow bits based on 
selectable word sizes of 4,8,16, or 32 bits. 

The only more capable unit I know of is the HP-16, but at $200-$500 
on eBay, they're becoming collectors items. Besides, I own an HP-16 , 
but still use my CM-100 most of the time.

The CM-100's seem to go for $30-$60 on eBay.

Here's another nice CM-100 pic with some of its specs:

...mine is a CASIO fx-451 scientific calculator.
And that's exactly what it is: decimal, binary, octal, hex, deg, rad, 
scientific modes, lots of physical constants (with units - was 
especially handy during school :-)), hex numbers enterd without shift 
or other special key and function keys for neg, not, and, or, xor, 
xnor, together with the usual trigonometry, algebra, 6 parenthesis 
levels and several stak memories (R, P, X, Y and M). Oh, and it is 
still very handy for newsgroups where americans post with its 
conversions between SI units and all this cumbersome F, gal, oz stuff ;-
)

Stefan,
How many digits in binary mode will it 1) calculate and 2) display?

Thanks,
Dave

Hi Dave,

it displays as many digits as the display has for the mantissa: 10

btw: Do you want a picture?

Stefan

If it's any help, in respect of the facilities offered by calculators 
when using binary functions, the Casio fx-992s can perform binary 
functions using up to 32 bits. The display can only display 8 bits, but 
you scroll through 4 screens to show the rest of the bits. There are 
single keypress functions for NOT, AND, OR, XNOR and NEG.
I have a more recent model that is programmable, but the fx-992s is very 
handy with the single keypress access to the functions.

Regards.
