You might find that it's just the zebra strip on the display that needs cleaning. It would be shame to ditch an old friend!
You might find that it's just the zebra strip on the display that needs cleaning. It would be shame to ditch an old friend!Yes, that's a common problem with small LCDs I've fixed numerous calculators, meters etc. just by opening them up and making sure the display is properly connected. If it's a plastic strip, it's probably better not to remove it, as it's difficult/impossible to reattach it: push it down firmly on the glass and hope for the best. If it's a silicone rubber strip with carbon strips then it can be cleaned but it's better to just try manipulating it while it's still on the display.
This is the latest:+1 for the fx-991ex :-+
http://www.casio.com/products/calculators/fraction-and-scientific/fx-991ex (http://www.casio.com/products/calculators/fraction-and-scientific/fx-991ex)
Has a new high res display and new engineering notation in the results.
I prefer the non-VPAM ones myself, but if you are used to VPAM then that's the one to get.
new engineering notation in the results.Does that New mean the one which mimics the SI-Prefixes, by hiding the exponents so you can calculate 3n*5G and calculator gives output 15. :-- :-// :-+
I like my HP 35s.. it doesn't feel as hefty or as robust as HP calculators used to feel, but it's still a very nice calculator with Polish notation.
Careful buying amazon.de calculators. Turns out the fx-991ex has german version.

yeah, i figures as much so i bought it on ebay. funny enough turns out the store was 15 minutes from home
though it could have been a good incentive to really start learning german >:D
How to Open a Calculator With the Command Prompt: http://www.wikihow.com/Open-a-Calculator-With-the-Command-Prompt (http://www.wikihow.com/Open-a-Calculator-With-the-Command-Prompt)I already knew that. I'm disappointed. I was expecting something about issuing commands to the Windows calculator via the command line so it can be controlled using a batch file.

I believe that English will be available for use under licenced conditions but the details of that will be part of the BrExit negotiations.
minus the app (i tried it several times but meh)That app almost perfectly resembles my vintage Casio fx-100v (I found it, it is still powering up! Never changed the battery. I remotely remember my mother having bought it for school, maybe mid 1980's). I like it because it is much better than the builtin Android calculator.
You don't even need a command prompt for this nowadays, just hit the Windows key and type the name of the EXE/COM:How to Open a Calculator With the Command Prompt: http://www.wikihow.com/Open-a-Calculator-With-the-Command-Prompt (http://www.wikihow.com/Open-a-Calculator-With-the-Command-Prompt)I already knew that. I'm disappointed. I was expecting something about issuing commands to the Windows calculator via the command line so it can be controlled using a batch file.
Any program can be started using the command prompt and if the program's folder is listed in the system path variable, you only have to type the file name of the program, minus the extension.

even better, why not greek? it all started from the hellenic union about 25 centuries ago, didn't itFair point. We should offer Greeks and Romans a discount.
Sadly my preferred calculator is the HP42s which goes for a staggering almost $400 on ebay.
I wish I hadn't lost mine. I have a hideous 33s that I bought in a hurry and I hate it.
Swissmicros is building HW calc based on the Thomas Okkens Free42 sources. Should be out about this year (hopefully) and beta units are soon send to testers I have heard. ;)Sadly my preferred calculator is the HP42s which goes for a staggering almost $400 on ebay.
I wish I hadn't lost mine. I have a hideous 33s that I bought in a hurry and I hate it.
I fortunately have 2 hp42s calcs (from new), still in great condition as my goto calculators. I run free42s on my android when away from the real ones, which is great other than it doesn't have the wonderful real clicky buttons...
cheers,
george.
Well they can sign me up!Here is a teaser for you, it is first publicly seen potrait form prototype.

https://www.youtube.com/watch?v=bU-_9x8dEM8I thought I was in a similar situation with my Radio Shack EC-4014 (which is a rebranded Casio something- pic is below) but if I recall correctly I think the fix was something like it just turned out that I needed to replace the internal battery which was draining current from the solar cell - with another slightly less dead hearing aid battery - and then put it in bright light.
The display had various glitches and also it would not switch out of the hexadecimal mode
This was quite some time ago. the calculator was purchased in the late 1980s or early 1990s. Now it seems to work after I put it under the light.
Putting the calculator in direct sunlight a bit helped.

It's on it's way!
Exciting! I'll be checking the mailbox a bit more often.
1. Buy an HP 50G
2. Learn how to use RPN
3. Feel your life improve tenfold.
RPN is the only good way to use a calculator.

Just wasted $20 on an fx991es (I lost my fx5800p a few weeks ago). It's totally crap, and it has practically no EMI survival capability in a high power electronics lab.50g ;) It also does have 3 wire UART and SD card for apps. ....And shielding. Plus https://www.maximintegrated.com/en/design/tools/calculators/hp50g/ (https://www.maximintegrated.com/en/design/tools/calculators/hp50g/) and metric tons of others.
I took it to a test bench and shorted a big capacitor nearby, then the calculator became dead, permanently.
My old fx5800p would only reset, but not die, when zapped with an electromagnetic zapper even in much closer close range and with much higher energy.
Has anybody seen the HP15C emulator software?I got my 1st UoAS degree with TI83+, then for the 2nd degree I got HP50g and in first 5 minutes just something clicked and I realised what were wrong in the world before :-DD (Programmin some handy routines on RPL is also so nice. A few key clicks (8 can create and run a new function/command, 2 creating a program object, 2 for new commands inside of it, 1 for closing it, 2 for name and storage and 1 for calling it) and you have a extended function set it your calculator).

Ive never used an HP, or RPN. After reading about the popularity of them over time and the Swiss Micro redo of them now I am bit curious about them. HAs anybody switched from one to the other, and of so what was your experience?

I have my new favorite perfect calculator I think!
It's still in beta labSpokane, check the forum.Good you got your favourite calc back. I must point out that they is more like a he as it is mainly a one and half man show what I have understood (from HP calc community).
I just requested access and they allowed me to buy one.
I paid the equivalent of about $120 USD.
Worth every penny.
Hey, calcs are personal devices. If you are satisfied in the old workhorse why to change. Just get a spare unit in case the fx5800p gets discontinued and turns to unobtinium (case of many HP classics) :-+Just wasted $20 on an fx991es (I lost my fx5800p a few weeks ago).

I eventually got another fx5800p. I'm so used to Casio's layout and I'm kinda reluctant to change.
