Anyone still using a classic calculator?

[Elektrishun]

Getting rid of some stuff and thnigs. I thought most of my calculators were long gone but I found a few more. The one I sometimes use at my workbench is a Casio fx-991MS. It has a little solar panel for charging. As well, I have a Texas Instruments TI-30XA, the big brute TI-84 Plus (monochrome display), and a Sharp ELSIMATE EL-344R (it has a solar panel too). Similar to old cell phones, open a drawer and suddenly there's another one. I'll keep the Casio but the rest will go to the second hand store.

With smart phone calculator apps or online calculators I rarely use the Casio but I find it comforting to know it's there.

I have a couple regular old calculators laying around that get used, one in the desk, one at the hangar, one in the truck

I do use the phone for a lot, its always in your pocket, and I have the various handy dandy apps for triangles and such that make it convenient

I have a couple in the shop specifically to not use the phone when my hands are (pick one): oily, resin gooey, over a swaf pile, gloved hands.... Easier on the wallet to replace a 10$ calculator

That's the same reason I have an old phone in the garage - for taking pictures when my hands are not clean enough to handle my good phone.

I still use a calculator in the office, the buttons on the phone are too small for long term use.

HP scientific. RPN all the way, baby.

Yes, I use my HP 35s all the time, Been a fan of RPN since the mid 70's, while using an HP 21.

Always have a couple of thrift-store calculators on the workbench. Better to muck up a $2 calculator than a $800 phone.

I still use a TI-84 regularly. Goes through batteries pretty fast though. I keep it around in case I ever have to rig a Dehavilland DHC-7 again. Not likely that will happen. It's the go to calculator for that. Unfortunately I lost the program for that job. I don't think I'll type it in again.

I still have two from university, and two new simple ones with metric conversion that I use in the shop.

Does your model of TI-84 have the color display and option for a plug-in power adapter?

Old calculators you say?

 

[DPittman]

Anyone remember these? New battery and it still works as good as ever. I can even still do my cheese head junior high school "trick" with it.

 

[YotaBota]

Had one in Gr12. Now moved up to the TI30 son (or grandson)lol.

 

[Maker Mike]

I have a TI89 that I use in the shop all the time. I don't trust myself with simple addition and subtraction.

 

[Janger]

Keep these old relics ... they will be useful again... when we decide $3K is too much for a phone!

That's not a calculator, this is a calculator.
