	Commodore AL-1000 Programmable Calculator
		Mathatronics, Inc. and their Mathatron calculators (circa late 1964) lay legitimate claim to the title of the world's first stored-program programmable electronic desktop calculator, almost three full years before the AL-1000 was introduced in Japan in October of 1967.
		The two working registers of the calculator, along with the memory registers, and 30 steps of stored program reside in a small magnetic core memory array, meaning that the content of the memories and program steps are maintained when power is removed from the machine.
		Calculation times of the AL-1000 are quoted in the operator's guide as 8ms (.008 second) for addition and subtraction, and between 20 and 200 milliseconds for multiplication, division, and square root, depending on the The square root operation is performed by the "sum of odd" numbers method.

	Programmable calculator - Wikipedia, the free encyclopedia
		Programmable calculators are calculators capable of being programmed much like a computer.
		Programmable calculators allow the user to write and store programs in the calculator in order to solve difficult problems or automate an elaborate procedure.
		Programming capability appears most commonly (although not exclusively) in graphing calculators, as the larger screen allows multiple lines of source code to be viewed simultaneously (i.e., without having to scroll to the next/previous display line).

	Calculator - Wikipedia, the free encyclopedia
		The type is considered distinct from both a calculating machine and a computer in that the calculator is a special-purpose device that may not qualify as a Turing machine.
		The first mechanical calculators were mechanical desktop devices, which were soon replaced by electromechanical desktop calculators, and then by electronic devices using first thermionic valves, then transistors, then hard-wired integrated circuit logic.
		Also, most everyday calculators do not follow the proper order of operations in mathematics; therefore, if someone were to type (on an average calculator) "2+4×2", they may get 12 (i.e., the answer to "(2+4)×2"), instead of 10, the correct answer (i.e., the answer to "2+(4×2)").

	Programmable Thermostats : ENERGY STAR
		Programmable thermostats automatically adjust your home's temperature settings, allowing you to save energy while you're away or sleeping.
		Programmable thermostats earn the ENERGY STAR by meeting strict energy efficiency guidelines set by the government.
		If you are like many homeowners and work outside the home during the day and have a different schedule on the weekend, a programmable thermostat can offer many benefits, and the return on your investment is usually within 1 year.

	Which Computer - Programmable Calculator
		The programmable calculator bridges the computer gap because it's approachable and personal: approachable because it is easy to use - almost self-explanatory, and personal becuase it's flexible enough to be tailored to your requirements.
		With the calculator and a peripheral plotter, a finished plot is ready in less time than it would have taken to calculate one point by hand.
		Calculators are useful for those jobs that fall in the gap - jobs that don't get done now, jobs that need your personal attention, and ones no one seems to have time to do.

	Electronically programmable calculator with memory package - Patent 4722065
		A calculator according to claim 1, whrein each of said plurality of memory package means has a card-like shape and comprises a random-access memory as a memory element, and a power supply means for backing up said memory element.
		In this calculator, all the addresses of respective memory areas of the plurality of memory packages loaded into the mechanism are considered as a continuous, single address area, and a program or variable data can be written in the address area.
		With an electronically programmable calculator of this type, in the program data setting mode, continuous absolute addresses are assigned to all the memory areas of a plurality of, e.g., loaded RAM cards which are considered as a single address area.

	Casio AL-2000 Programmable Calculator
		To calculate a square root on the AL-2000, the user enters the number to have its root extracted, presses the "divide" key immediately followed by the "=+" key to calculate the result.
		The logic to implement such an architecture, as opposed to the fully bit-serial adders of earlier calculators, was too complex to implement using discrete components, but the Philco integrated adder and complimenter made the parallel addition (or subtraction) of two BCD digits possible.
		Compared to the programmability of a competitive machine of similar design timeframe, the Hewlett Packard 9100B, the AL-2000 is very limited in its capabilities.

	Programmable Calculators: Calculator Programming
		On a keystroke programmable calculator you're familiar with, you can write fairly sophisticated applications quickly, easily, and without as much as glancing at the manual, which is certainly not the case with calculators that use a symbolic programming language.
		The calculator programmer who became familiar with the concept of indirect addressing, found on many of the more sophisticated programmable units, will have little or no difficulty grasping the concept of a C pointer later.
		At the same time, a keystroke programmable calculator uses the familiar decimal number system, and accepting input from the user or displaying a result is trivially accomplished.

	Calculator Policy - Faculty of Engineering - University of Alberta
		Calculators purchased elsewhere can be brought to the Dean's Office or one of the Department offices where the appropriate sticker will be affixed to the calculator.
		It should be noted that instructor approval of calculators means that the instructor in any course can choose to exclude programmable calculators from examinations if he or she chooses to do so.
		When it is determined that a student's calculator is either unapproved, ie it does not have the required sticker, or is the wrong type for that exam, ie programmable whereas only non-programmable calculators are allowed, the calculator will be confiscated and returned at the end of the exam.

	Programmable Calculators and Mathematics
		In the case of graphics calculators, some of these operations may be rather sophisticated, such as drawing a graph of a function or constructing a regression line.
		The leap from performing a calculation on a calculator to writing a program to do it is often not very large, and so it is likely that someone familiar with their calculator will find the writing of short simple programs easier than they might otherwise expect.
		Programmable calculators give access to a powerful personal tool for secondary students, and there seems to be a case for considering some ways of exploiting this.

	Bill Casselman - Linear algebra with a Java-based programmable calculator
		For a course in linear algebra taught in the Spring of 1999 to engineering students at UBC, I developed labs and coursework using a a Java-based programmable calculator, somewhat reminiscent of one of the high end HP graphing calculators.
		Success with students depended very much on how closely an instructor integrated the calculator into general course material, but the potential seems to be enormous.
		Among other things, it is very simple to extend the calculator's capabilities with a very small amount of Java program coding.

	Application Development Trends - Review: C Sharp Programmable Calculator
		This is indeed a calculator for your PC that uses RPN (you know, enter the operands first and then the operator, so to add 2 and 2 you press 2 Enter 2 +).
		But what makes it potentially interesting to developers is that it has a bunch of programmable buttons (6 in the free version, 200 in the registered version) that can be programmed by writing C# code.
		The calculator has its own integrated code editor, and it recognizes public static functions as things that should be exposed on the calculator keys.

	HP Virtual Museum: Hewlett-Packard-65 programmable pocket calculator, 1974
		The HP-65 was HP's fourth handheld electronic calculator and its third scientific calculator.
		Nicknamed "Superstar," the HP-65 was the first magnetic card-programmable handheld calculator, which is why some call it the "world's first handheld computer." The HP-65 could read from and write to magnetic cards, allowing the user to buy program cards from HP or save programs on cards.
		Although the HP-65 was similar to the HP-35, HP's first handheld scientific calculator, new features included a card reader, the slot to hold a card below the display and the second slider switch to select program or run modes.
