I still remember the graphing calculator I used in high school, even though I no longer needed to graph parabolas because of the price, size, and features. The Internet Archive made it easy to relive those days by launching a series of clickable online calculator emulations.
The calculator drawer, unveiled Sunday, contains 14 calculators. Mostly from his Texas Instruments, including my old TI-83 Plus and his 1995 Texas Instruments TI92 like handheld console. However, there are some HP-made options as well. The oldest calculator is a 1989 VTech Electronic Number Muncher toy.
In addition to keyboard input support, Calculator allows you to type by clicking on-screen buttons, making for an even more realistic experience when using emulation on a touchscreen. Some even have buttons and sound effects.
Calculator uses the Multipurpose Emulation Framework (MAME) team emulator that has been emulating thousands of vintage platforms and gadgets such as computers and arcade machines for 25 years.
Calculator manuals are also uploaded to the Internet Archive for those who need to brush up on their calculator skills.
The Internet Archive blog post announcing The Calculator Drawer details the emulation process. We focused on the challenge of emulating a small set of his LED lights or LCD numbers while incorporating the rest of the gadget, a largely unchanged chassis.
For “rendering emulated devices that require ‘extra’ drawing to extend the device’s screen or light-reflecting parts,” as the Internet Archive puts it, they used MAME’s artwork called the function. MAME artwork allows The Calculator Drawer to display a calculator image on screen while supporting interactivity. Also, “deep knowledge of programming” is not required. This method has been selected beyond his MAME’s ability to create vector-based drawings and calls for volunteers to provide high-quality photographs of old-fashioned techniques.
Calculator Drawer is a fun way for math geeks to reminisce about memorable gadgets, albeit smaller than the Internet Archive’s other collections. You can also use advanced calculators that cost about $100 or more for free.
