The Evertop is a DIY open-source project aiming to create a modern, portable, and extremely low-power IBM XT compatible computer. It features a 4.2" e-ink display, mechanical keyboard, and boasts over 100 hours of battery life. Based on a Raspberry Pi Pico microcontroller emulating an NEC V20 processor, it can run original IBM XT software and DOS games. The project includes custom-designed PCBs and 3D-printed case files, making it reproducible for others. While still under development, the Evertop represents a unique blend of retro computing and modern hardware for a highly portable and energy-efficient experience.
Byran created a fully open-source laptop called the "Novena," featuring a Field-Programmable Gate Array (FPGA) for maximum hardware customization and a transparent design philosophy. He documented the entire process, from schematic design and PCB layout to firmware development and case construction, making all resources publicly available. The project aims to empower users to understand and modify every aspect of their laptop hardware and software, offering a unique alternative to closed-source commercial devices.
Commenters on Hacker News largely praised the project's ambition and documentation. Several expressed admiration for the creator's dedication to open-source hardware and the educational value of the project. Some questioned the practicality and performance compared to commercially available laptops, while others focused on the impressive feat of creating a laptop from individual components. A few comments delved into specific technical aspects, like the choice of FPGA and the potential for future improvements, such as incorporating a RISC-V processor. There was also discussion around the definition of "from scratch," acknowledging that some pre-built components were necessarily used.

Hacker News commenters generally expressed enthusiasm for the Evertop project, praising its unique combination of retro computing and modern e-ink technology. Several highlighted the impressive battery life and the appeal of a distraction-free writing device. Some questioned the practicality given the slow refresh rate of e-ink, particularly for gaming, while others suggested improvements like backlighting and a more ergonomic keyboard. A few commenters expressed interest in similar projects using different retro hardware, such as the Apple II or Commodore 64. There was also discussion about the challenges of sourcing parts and the potential market for such a niche device. Several users shared their personal experiences with similar e-ink projects and offered technical insights.
The Hacker News post about the Evertop, an e-ink IBM XT clone, generated a fair amount of discussion, with many commenters expressing enthusiasm for the project.
Several users focused on the impressive battery life. One commenter questioned how 100+ hours was achieved, prompting a reply explaining that the low-power nature of e-ink displays is the primary contributing factor. This led to further discussion about the power consumption of different components in the system and general power optimization strategies for low-power computing.
The choice of an XT clone as the basis for the project also sparked conversation. Some users reminisced about their experiences with XT machines, while others questioned the practicality of the platform in a modern context. One commenter suggested that a more modern, but still low-power, platform like a Raspberry Pi might be a better choice, offering more flexibility and software options. This prompted counter-arguments about the simplicity and robustness of the XT architecture, and its suitability for specific use cases where a full-fledged operating system isn't necessary.
The e-ink display itself was a major point of interest. Some commenters expressed concerns about the refresh rate and its limitations for certain applications, particularly those involving animation or video. Others highlighted the benefits of e-ink in terms of readability in sunlight and low power consumption, suggesting applications like e-readers or dedicated coding environments. The discussion also touched upon the different types of e-ink displays and their varying characteristics.
Several commenters expressed interest in purchasing an Evertop, inquiring about pricing and availability. There was also discussion around the potential for DIY builds, with some users sharing links to similar projects and resources.
Finally, the developer of the Evertop, Eric Jenott, participated in the thread, answering questions about the project's design choices, technical specifications, and future plans. This direct interaction with the creator added significant value to the discussion, providing insights not available elsewhere.
