OT: Aw s....

Nerds. When your relationship with your calculator is the most durable..

Quite happy with my limited edition HP15C (bought a few years ago). It really does have the great keyboard and the long battery life of the ASIC-based originals.

Not quite. While I still have the HP45, I've had the wife two-and-a-half years longer than that. ...and she's not just taking up shelf space. ;-)

Long battery life of the originals? Do you mean the "original" CMOS (C-series) calculators?

My 11C just came in the mail today.

I spent countless hours exploring and figuring with my first calculator, and it's still in perfect working order. An HP was out of the question, but this was RPN, so I was much quicker at calculations than anyone around me at school:

The Sheen 1000 displays 8 digits, but has ten digits internally. I worked out how to do multiple-precision arithmetic with it, calculating the 12th root of 2 to 14 decimal places - far more than needed to place the frets on the guitar I built in 1976, but I was curious about numbers and calculating technique. My first proper computer program printed a table of fret spacings.

I have a simple cardboard version of that from 1973, which got a fair bit of use:

I think I probably used it a little more than my conventional Japanese one:

I also had an antique one with ivory scales, but I can't recall what happened to it. I think it had been my grand-father's, so probably about 1920's or -30's vintage.

I never loved the HP-27S as much as any of them, and now I use the computer or a phone app like everyone else.

My eBay purchase of another TI-60X came today... in much better condition than my original!

I also bought a TI-30X Pro... passable... I can live with its quirks, so I'm covered to EOL (my own ;-) ...Jim Thompson

I had one of those! Thanks for the memories.

Ah :-D Indeed may be I was a Nerd at the time and ten years after I meet my wife ... BTW she catches immediately how is works RPN notation (operande, operande, ... op code)

Anyway I repeat NOBODY !

It arrived yesterday... in better condition than mine that died... rubber feet still intact, clean keyboard, etc :-[

It's not to-o-o-oo bad... takes a little getting used to, all that multiple pushing the same key.

...Jim Thompson

Did you buy both a replacement TI-60x and a TI-36x?

Yep. My calculator works well for holding open a book or report while I have both hands on the computah keyboard.

My caclulators: etc...

Of course, Google Voice: and Wolfram Alpha:

I'm slightly impressed by the Breitling Navitimer with the integral slide rule on your link. Probably the most expensive slide rule ever made.

Any iIdiot can calculate the tip with a smart phone, but how big a

--sp

Yep

I _design_ chips and write simulation models in my head and on paper, assisted by my trusty calculator(s) that do(es) hyperbolic functions.

Computers and simulators are for VERIFICATION.

For holding books open I have several of those nice leather straps with lead weights on each end.

Calculating a tip is hardly rocket science... I do it all the time _by_hand_ on my copy of the receipt... 15% of the BEFORE-TAX amount for good service, 20%+ for exemplary service... $1 and a nasty note on the card copy for bad performance ;-) ...Jim Thompson

Me ? A big Engineer. I'm on Vacancy this week, please do the same instead of placing those shit comments.

Sounds like it's a well-needed vacation.

Kind of depends on how expensive the meal is. If the meal is inexpensive , then most of the dinners will not be tipping very much. So you really ought to tip a bit more to make up for the cheapskates.

And as far as whether the tip should be calculated on the before tax or after tax amount? Well the waitress is having to pay taxes too. So I tip about 20% on the total bill for average service.

So very strange. For small calculations I use a spreadsheet, or if I'm too lazy to open that, I just use Google's built-in calculator. Actually, I u sed it just a few hours ago to calculate motor efficiencies.

I gave the calculators to the kids, and it would take me more time to hunt for the things than it would to just open a spreadsheet... the TI-85 brings back memories from Linear Algebra, and the Casio FX-115MS+ was what I used for the PE exam... (only a few kinds of calculators were allowed for that exam.)

The more you work the more you get paid. But if the more you get paid the more you pay then why work more? Socialism illustrated in Norway.

That's the way I tip. Basically, if it's a sit-down meal with full service my minimum tip (reasonable service, obviously) is $6, for two people. I don't tip at all for counter service.

What the waitress pays in taxes isn't of interest. The convention is to tip on the pre-tax amount. It's not generally paid on the government's piece of the pie. I do, though, mostly because it's easier. I don't generally leave a bunch of change on the table, either, unless it rounds the tip to the even dollar. I also try to pay the tip in cash, whether I pay the bill in cash or by card.
