Ask Slashdot: Calculators With 1-2-3 Number Pads? 393
dotancohen writes "Although the telephone has the 1-2-3 key on the top row, most calculators and keyboards have 7-8-9 on the top row. Switching between the two destroys muscle- and spatial- memory. Do any slashdotters use a scientific calculator with 1-2-3 on the top row? I've already scraped and resoldered my Casio fx-82 calculator to have 1-2-3 on the top, and remapped the numpad in Kubuntu, but if there exist any calculators like this already on the market, I'd buy two."

When ATT went to push button phones, they intentionally put the numbers backwards from 10 key adding machines everyone used back then. Then didn't want the fast typers to outpace their new phone system and punch the numbers in to fast.

On a side note, back in my teens, I would make $5 for swapping the top and third rows of buttons on a standard WECO 25xx phone so that they matched an adding machine. The ladies in the office loved it.

My understanding is that Bell Labs tested a number of layouts before settling on the 1-2-3 matrix we use now as being simplest to master (see R. L. Deininger, Human Factors Engineering Studies of the Design and Use of Pushhutton Telephone Sets [alcatel-lucent.com], 1960, Bell System Technical Journal [PDF]).
I'm not sure if calculator / comptometer manufacturers had their competing studies; I've heard that when Bell asked for an explanation, the answer was a shrug...comptometers were about 80 years by then, so I think the origins of their layout are as opaque and full of folk explanations as the QWERTY layout.
Regardless, I've encountered OP's request before...but for phone layouts which matched calculator layouts. I was working in an operations office a few years ago run by a person who was a fan of "Cheaper by the Dozen" who wanted to optimize our phone dialing speed (this was a fun place to work, even if this request sounds odd). We didn't have any success, but it was an interesting thought.

There are good reasons for the two layouts. They're lost in the mist of time, but they are good reasons.
Calculators derive their layout from a strictly mathematical perspective, and is probably the most sensible layout to work with if you want to practice your muscle memory.
The phone layout is that way due to the mapping of letters to the digits, which was defined back in the days of rotary dial phones. Putting the 'ABC' key at the top of the keypad made it easier to read. In addition, the in old pulse-dial system, the zero digit actually represented ten, not zero, and on rotary dials it was placed at the end after nine. That also helped to make the chosen key layout for phones seem more logical at the time, both for the phone manufacturers and for users who were used to rotary dials.
One thing you certainly aren't going to achieve is to get calculator or phone manufacturers to change their layouts. Both layouts are highly ingrained in the collective consciousness of their users, and no-one is going to buy a product which deviates from the norm. You may as well try to persuade everyone to go and buy a Dvorak keyboard.
So the short answer to your plea is: no. It ain't gonna happen.
But I can see hope for you: Smart phones.
While you aren't going to get calculators to change, smart phones have touch screen interfaces. I don't see any reason at all why there couldn't be an app that displays the phone keypad in calculator-like style. It may be the opposite of what you're asking for, but it would achieve the consistency that you're looking for between the two.
The only problem then is if you ever have to use someone else's phone to make a call....

Either way, it's a wasted question. Years ago, when Ma Bell was the only phone company and they came out with touch-tone phones, they patented the arrangement with 1-2-3 at the top. So if you want to make a calculator that uses that, you'll have to pay a fee.
That's not true. There's no patent for the 1-2-3 keypad (nor was Bell/AT&T the only phone company in the US, but that's not relevant here). Calculators in the form of mechanical adding machines predated the DTMF keypad by decades. When Bell came up with the touch-tone system, they actually spent a lot of money researching whether it should be adding machine layout, or 1-2-3 from the top. As it turned out, even experienced ten-key operators were able to dial phone numbers faster on the 1-2-3 pad because everyone--- even tenkey operators--- approached the task of dialing a phone with their index finger alone, regardless of whether it was pushbuttons or dial, because they were already in the habit of doing so with dial phones. 1-2-3 keypads are faster to use when visually hunting and pecking with one finger. Given that no one was ever going to be doing rapid data entry on a phone, it made more sense to use top-to-bottom order, because the reverse order of tenkey exists only to make rapid multi-digit data entry faster (i.e. zero under the thumb, pinkie for enter, and most common digits under the fingers as per Benford's Law)
I don't know what the hell is wrong with the OP that his brain doesn't have room for two different keypad layouts.
