The Evertop is a portable, ultra-low power PC that emulates an IBM XT with an 80186 processor and 1MB RAM, featuring a 5.83 inch e-ink display, various peripherals, and a solar panel for charging. It can run for hundreds or thousands of hours on a single charge and supports old operating systems like DOS, Minix, and Windows up to version 3.0. The device is designed for low-power retro computing and has a minimal version called Evertop Min, which reduces weight, material, and costs. The Evertop's goal is to provide a virtually unlimited amount of software, games, and programming without running out of power.
