New Casio calculators

[smjcuk]

Can't wait until these show up in my half of the world:

Finally added engineering symbols to their top end scientifics and a nice new high res display:



Beats poking the ENG button after every damn calculation too.

Edit: Oh and they do a version that takes proper AAA batteries rather than LR44s!

[Harrkev]

Ohhhh.  "PLASTIC KEYS!"  Hooray!  My prayers have been answered!   

Sorry, no RPN, no money from me...

Nice, but I still love my FX-5800P introduced in 2006.
But I think that after 10 years they might introduce a new model. So let's see in 2016.

I also have Casio FX 991 ES PLUS. I don't like that the computation history disappears when I press the ON button.

Replies inline:

I own an RPN machine (well RPL); an HP50g. It doesn't get used. I'm pretty sharp with RPN/RPL having had a 50G, 35s, 48GX and a 15C and written numerous programs for all but the Casio is just right. Its also a ton faster than the 50g and doesn't have a stack of manuals 4 inches thick! I'm not sure HP deserve the reputation they have either as anything since the 15C has been pretty crappy.

Re FX5800P, they're pretty difficult to get in the UK with English instructions and legend in the cover otherwise I'd probably have one. If someone knows a source I'd be grateful.

As for the 991ES PLUS power on memory clear out, I can't count one problem I've had with that as I don't heavily use the history. I tend to use A, B, C, M as accumulators which are persistent.

Some very early Casio's had engineering notation mode. I thought the 991ES had it? but I can't find mine now...
And that screen, very nice, 12096 dots, 4 times the res of previous ones.
I might have to get this new fx991ex, but can't find it available anywhere?

ES doesn't have engineering mode. It has an ENG button you whack to convert the result to engineering mode but that is it. That's stupidly annoying when you're doing lots of calcs though.

Casio stuff takes a year or so for it to appear on the market based on the time I had to wait for the ES PLUS.

Most old Casio's have an ENG mode, but I've rarely use it, I prefer to use the ENG button when possible.
I do like the ENG notation when used in formula based entry and display though.

The FX-115MS and FX-991MS support proper engineering notation. You can enter values directly in milli-this, micro-that, and get an answer with the correct suffix.

Still can't quite believe I went through my entire degree course typing things like E-9 instead of 'n'. So unnecessary.

[smjcuk]

Yep. Tempted to snag a 991MS actually if that is the case. That's what's killing the ES PLUS for me. It's perfect otherwise!

50% of the errors I make are miskeying the exponent and then carrying that through. Next thing I know, that 10k is a 1M and I'm going hmmm that doesn't look right.

My own fault for being incompetent at the end of the day but every little helps...

[AndyC_772]

They're both discontinued now, sadly, though you may still be able to find one or the other.

The last one I bought was this model:

The FX-115MS+ appears to be a current model with engineering notation, you can just about make it out printed above the number keys:

Thanks for the links. There's actually one on gumtree about a 30min drive away from me so will snag that today or tomorrow if I can shift my workload elsewhere (calculators are far more interesting than designing API specs)

[smjcuk]

Thanks for the info.

Good point about the menus. I have an HP50g which does engineering units but the unit items are buried in about 3 levels of menus which kills it for me. In fact that's one of the things that kills the entire device for me. Even if you assign the menu to a user key it's 3 keypresses away. Shift+key should be as deep as you need to go in an engineering calculator.

991MS might be the pinnacle here TBH.

Either that or the HP 35S but they appear to be buggy and poorly made.

[AndyC_772]

Oh, dear, what a wasted opportunity 

Such a clumsy method of entry, especially for a product which - you'd hope! - was actually designed by engineers!

Entry, clumsy SWAP method?. Product hope DUP which especially ROLL engineers designed for? you'd.

STACK UNDERFLOW

Edit: just to add, I was once an RPN/RPL zealot. That was until I had to untangle a non-trivial RPL program I wrote and get it working in mathematica. In recent years, I've discovered that it's not the entry method that counts but the calculations you're doing.

[AndyC_772]

Lol I didn't mean RPN, I meant having to enter OPT 3 before each engineering symbol 

[smjcuk]

Aaaaaaaaaaaaaaaahhhhhhh 

Fail on my part. Please accept my apologies

so used to defending myself from Apple and HP fanboys

[EEVblog]

The shifted engineering entry is no better than normal EXP entry on positive units, you still have to press two buttons to enter positive units e.g. SHIFT k
So no advantage over normal calcs where you hit EXP 3
Only an advantage when you have to enter negative exponents, so SHIFT µ instead of EXP - 6, or worst EXP - 12

I never cared too much for the engineering entry, I usually preferred using the EXP key. Keeps things consistent when I move between calcs with it and without it.
And the shift key is always so far away, big hand movement.

[smjcuk]

Very good points there actually.

[SteveyG]

I don't see the engineering symbols on any keys though 

[EEVblog]

There aren't. It's engineering notation display mode only.
Almost all Casio calcs have an ENG display mode feature, along with SCI and FIX and NORM, but in this case it displays the actual symbol instead of the exponent number.

So it's on the website but no one in the world sells it yet?

[EEVblog]

I love this little FX-260


Still a current product!
The smallest scientific they make, and the only calc with the old school pre-VPAM function.
No ENG mode, and shifted 1/x and X-Y keys, but the compact nature of it I just really like.
I really do hate VPAM! unless it's a full on complex equation I'm trying to enter and solve, and in that case I want to use the big screen calcs for that.

Yep. Sucks. Always does. Even Microsoft deliver before Casio.

[EEVblog]

I remember a pre-VPAM Casio that had a small dot matrix display just for the exponent part. It could display engineering symbols or regular exponent numbers, I thought that was the ducks guts at the time. This is before full dot matrix display and full line dot matrix/segment mix display came around.
Can't recall the model number though, anyone?
