Fresh from the Eighties: The Evertop is a retro-system as resilient as it is nostalgic, built to keep running off the grid for days. With impressive hardware support and ultra-low-power features, it offers a practical, long-lasting DIY project for retro computing enthusiasts eager to relive the past.

Custom-built devices for running vintage PC software are trending, with new models embracing different approaches to retro emulation. Unlike the Book 8088, which featured a genuine 8088 CPU for maximum authenticity, the newly launched Evertop uses an Espressif ESP32 microcontroller. It emulates an IBM XT-class machine with an 80186 processor, prioritizing accessibility and portability over period-accurate hardware.

Programmer and tinkerer Eric Jenott designed Evertop as an open-source, ultra-low-power PC that runs on three different power sources. The device features two 10,000mAh batteries, a built-in solar panel, and a USB port combined with “extreme power saving measures.” Evertop could potentially operate for hundreds – or even thousands – of hours on a single charge using Jenott’s configuration.

Jenott noted that Evertop can run classic operating systems like DOS, Minix, and other software as if it were the 1980s again. It even supports early graphical environments such as Windows 3.0. Naturally, it can run Doom – though the experience is less than ideal, offering a garbled, sluggish rendition of the iconic shooter that’s more novelty than nostalgia.

Jenott posted a comprehensive video gallery demonstrating Evertop’s capabilities, including classic DOS games and basic QBasic programs. The device uses a 5.83-inch grayscale e-ink display with a 648×480 resolution and supports full CGA, Hercules, MCGA, and partial EGA/VGA video modes. Audio options include PC speaker, Adlib, Covox, and Disney Sound Source. Unfortunately, it lacks official Sound Blaster support.

Evertop isn’t just power-efficient – it also supports a wide range of peripherals. It includes PS/2 ports for keyboards and mice, serial connections, an SD card slot, and USB for faster file transfers. For connectivity, it offers Ethernet, Wi-Fi, and LoRa radio. Although the hardware supports Bluetooth, Jenott hasn’t yet activated any features that use it.

Jenott hasn’t yet provided purchase or pre-assembly options for Evertop, meaning retro enthusiasts must follow the project’s documentation to build it themselves. He also has plans for a “Mini” version that offers the same core features as the original model but lacks an integrated keyboard.
