An independent developer proved that Windows 10 can be light enough to run even on a calculator. He installed the Windows 10 IoT Core version, made for the Internet of Things, in a Prime Graphing Calculator, HP’s color touchscreen model. The handset has modest hardware, with a specification that includes a 400 MHz processor, 32 MB RAM, and storage of only 256 MB, about two thousand times less than a traditional computer.

Windows 10 IoT Core is a simplified version of the system for devices like Raspberry Pi. It doesn’t support complex programs made in the classic way of the system, but it can run apps available on the official store. Still, the developer was forced to make some adjustments so that the calculator could identify the software.

User @imbushuo described the process on Twitter last week. First, he showed that there was a conflict that prevented Windows 10 from booting and, because of the small screen of the calculator, he couldn’t see the error code. Two days later, he returned to the social network to confirm that a simple adjustment in the memory management unit made it possible for the Microsoft system to start.

So far, the developer has not detailed the procedures he carried out on the device to enable it to become compatible with Windows. He didn’t make it clear which system resources are working and which can’t be used because of the limitation imposed by the hardware. The project is available for consultation in the GitHub repository.
