The Kixmiller Pigeon. Who needs TI when you have Casio. Judging from the large screen, I already new that this calculator had graphing capabilities. I didn't know the historical significance that this piece of handheld electronic. The Casio fxG was the first widely used graphing calculators available for the public.
It was introduced in , and sold until when more advanced calculators hit the market. This calculator also had a programming mode which had bytes of memory. The display is monochrome, and their is no color or gray-scale video modes. Their were 82 mathematical functions built into the calculator. The calculator had no working batteries in it. It uses the CR lithium batteries. After buying new replacement batteries and discarded the dead ones, the calculator came alive.
Eventually, I was able to perform graphing operations, and do those cool graphs on the screen. Their is a online version of the original user's manual that covers the graphical and programming functions.
It was hard to understand the instructions though as the online manual was poorly scanned. One thing to note is that their were two releases of this calculator, the G and GA. Their are only small cosmetic differences between the two series of calculators.
The GA, which I have, was a later revised version of the G that was released in The condition though wasn't the best in the world, as some idiot sketched "CS" on the metal cover on the back of the calculator. Since this calculator had a programming mode in it, I've attempted to program the calculator. The programming language, along with the awkward layout of the keys, made programming difficult to say the least.
Their is a program which draws the Mandelbrot design on the screen. However, I heard that it takes a couple of hours to draw the design on the screen, and it drains the three CR 3-Volt batteries in the device. Those batteries are expensive to replace. However, I like the old-skool, retro design. It's 's nostalgia come alive. Typing text of this calculator was very awkward, and it took a few minutes to type the message in the display.
Closeup of the display. You can even see the pixels! Sample graph drawing the sine wave. Another graph. Me drawing random crap on the display! I've loaded Pockemul onto my computer. Pockemul is a emulator which emulates the handheld devices from the 's-early 's. The program emulates a Casio fxG graphing calculator, which is a close cousin of the G. I've attempted to program the emulated calculator as well. However, calculator programming is very difficult, and I couldn't get anywhere within the emulator either.
I will probably do a separate article about this program in the future. Classic Systems Emulated: Windows 3. Follow Us. Create your website.
Old Hardware Revisited - Casio fx-7000GA Graphing Calculator
This calculator is identical to the fxG in every respect apart from minor cosmetic differences. Both calculators have 82 scientific functions. From the image at the top, you can see the keyboard and the functions that are available, and the manual is the best place to learn more about them. One of the interesting features of this calculator was the ability to express multi-statement functions manually and in program mode.
Casio fx-7000GA Handheld Electronic Calculator
The Casio FXG is a calculator which is widely known as being the world's first graphing calculator available to the public. It was introduced to the public and later manufactured between and c. The calculator offers 82 scientific functions and is capable of manual computation for basic arithmetic problems. The calculator can compute basic arithmetic functions with a precision up to 13 digits.
