Casio Programmables

.

Japan's oldest calculator manufacturer, Casio is also the most prolific maker of calculators in the world. I already have more than 100 programmable models listed, and I see no end in sight!

Given the number and apparent popularity of Casio's models, it is a bit of a surprise to see how uninspiring many of their products are. This is especially true of their higher-end products that feature a mediocre programming model and a lack of functional integration between the calculator's various features. In contrast, many of their lower-end models are surprisingly versatile, and their oldest products are by far the most interesting.

Keystroke Programmables

Casio has been producing keystroke programmable calculators for nearly three decades. Over the years, several programming models emerged; some were short-lived, some has been used in several generations of products.

The Beginnings Casio's began producing calculators in the pre-LCD era; their first programmable models used vacuum fluorescent displays. Their first LCD models were also unique, true competitors to more expensive contemporary models such as the HP-41C.

Programming in the Blind A particularly annoying "feature" of many low-cost programmable calculators is that they provide no feedback during programming. On these calculators, your calculations are performed as normal when you are entering a program, instead of showing up as a list of (editable) program steps.

Advanced Keystroke Programmables Fortunately, Casio also produced some advanced keystroke programmables. Many used the same programming model that is found in their graphing calculators, providing labels, subroutines, and other sophisticated functions. Most importantly, on these machines it is possible to review and edit programs.

Formula Programming Formula programmables provide storage for formulae in algebraic form. While this method is convenient for students and, to a lesser extent, casual users, most formula programmables offer no true program control capabilities, such as branching, loops, or conditional execution. Worse yet, it is often difficult to use predefined constants in formulae, as these calculators have the annoying habit of prompting for all variables used in a program, whether you mean them to be user-entered or not.

(Mostly) BASIC Pocket Computers

Pocket computers programmable in the BASIC language were, and still are, Casio's specialty. Over the years, several different product lines emerged, but they all shared some distinguishing features, such as a MODE button that lets you select between calculator and program modes, and a standard set of ten program areas. Most of these calculators had an I/O port, making it possible to attach the calculator to an external printer or tape recorder interface. Some machines had a built-in printer.

The Classic Look Landscape layout, a small QWERTY keyboard, an optional numeric/scientific calculator keyboard, a 10-32 character LCD dot matrix display: this was the typical appearance of a BASIC pocket computer in the 1980s.

Folding Design The pros: a folding calculator's display and keyboard are completely protected when the unit is closed. The cons: increased fragility, difficult to use in one hand. Is the trade-off worth it?

C Programmables Yes, Virginia, there is such an animal: a handheld calculator with a built-in C-language interpreter/compiler. I wonder what it says about the respective educational markets that whereas the most popular calculators in North America are non-programmable scientifics with a fraction feature, in Japan C-language handhelds are surprisingly popular.

Graphing Calculators

Casio invented the graphing calculator.

No, it wasn't Hewlett-Packard; much to my surprise, I found out that Casio's first graphing model, the fx-7000G, preceded HP's first graphing machines by at least a year or more.

Unfortunately, like so many other Casio models, the fx-7000G is, well, uninspiring. HP's first graphing model, the HP-28C, offered a whole new paradigm for programmable calculators, one that combined keystroke programming with advanced object-oriented features. In contrast, the fx-7000G lacks functional integration and, in many ways, graphing is more an afterthought than an integrated feature.

Then again, HP used to be making engineering tools, whereas Casio's machines were designed for classroom use. Easy to use is not the same as easy to learn.

Casio continues to be a leader in the graphing calculator field; in fact, Casio remains the only calculator manufacturer producing a graphing model with a color display. No true RGB color yet, but nevertheless it's an impressive accomplishment with a non-backlit LCD. And despite my earlier comments, I do occasionally come across Casio graphing calculators, like the fx-7500G, that are a pleasure to use.

Student Models Casio graphing calculators are clearly designed with the educational market in mind. For better or for worse, the goal is not to create an engineering tool but a learning instrument.

Color Graphing LCD Casio's color graphing calculators represent technology's inevitable march forward. Although these relatively primitive displays are not true RGB, they help the user (the student, probably) create two-color graphs, for instance, that make it easier to demonstrate certain mathematical principles.

Miscellaneous/Unidentified models

There are several Casio programmables that I have not yet held in my hands, and therefore I don't know any details about them.

Miscellaneous/Unidentified Business models, calculators that are reportedly programmable in C, and other unidentified models are listed here that are still missing from the collection.

Variants/OEM Versions

Several Casio calculator models were sold under various OEM brand names, including the earliest machines. These OEM manufacturers include well known names such as Tandy/Radio Shack in North America and Privileg in Europe. Even the Russian manufacturer Elektronika marketed a model obviously designed and manufactured by (or under license from) Casio.
