content: Can't wait until these show up in my half of the world:http://www.casio-intl.com/asia-mea/en/calc/scientific/classwiz/fx991ex/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!

content: 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.

content: Quote from: smjcuk on April 13, 2015, 04:13:30 pmSome 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?

content: 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.

content: 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.

content: 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...

content: 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.

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.

content: 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 kSo no advantage over normal calcs where you hit EXP 3Only an advantage when you have to enter negative exponents, so SHIFT µ instead of EXP - 6, or worst EXP - 12I 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.

content: I love this little FX-260Still 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.

content: 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?

content: Yeah definitely. I had a 92 and I regret selling it. Wasn't a 92+ model though so it had pitiful RAM. The screen was crap though unless it was under direct light. CAS was buggy as hell too but you can't upgrade the 92 without a plugin module which is impossible to get.I've had an eye open for a voyage 200 bargain since but one hasn't turned up.NSpires are horrid though which put me off TI a bit. An 83 would really do me to be honest but the stupid idiot who designed it made the exponent key shifted.I'm such a calculator geek.

I have a TI-89 which is basically the same thing minus the extra alphanumeric keypad. I am really missing my good old Sharp calculator where calculating something didn't require minutes of key pecking and menu hunting ...

As well as f, p, n, mu, m, k, M, G, and T, the dot matrix will also display an "i" in complex mode when displaying the imaginary part of a complex number. I presume the very similar 570D/AC/AD, 115D, and 991D do so as well.
