E-ink IBM XT clone with solar power, ultra low power consumption, and ultra long battery life.
Evertop is a portable PC that emulates an IBM XT with an 80186 processor and 1MB RAM. It can run DOS, Minix, and some other old 1980s operating systems. It also runs Windows up to version 3.0. Because it's based on a powerful yet very low power microcontroller, uses an e-ink display, packs two 10,000mAh batteries, and implements extreme power saving measures, it can run for hundreds or even thousands of hours on a single charge. Combine that with its built in solar panel, and you should be able to use it indefinitely off grid without ever having to worry about battery life.
