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.
The MSXbook OneChipMSX is a compact, portable MSX2 computer contained within a book-like form factor. It features a Raspberry Pi RP2040 microcontroller emulating a Z80 processor, offering a faithful MSX2 experience. The system includes a membrane keyboard, a small LCD screen, integrated SD card storage for ROMs and data, and various ports for connecting peripherals like joysticks and external displays. Intended for retro gaming and MSX development, the OneChipMSX aims to provide a convenient and affordable way to enjoy the classic MSX platform.
Hacker News users discussed the OneChipMSX's appeal stemming from nostalgia for the MSX standard, particularly in Europe and South America. Several commenters reminisced about their experiences with MSX computers in their youth. Some expressed interest in the device but questioned the high price, while others debated the practicality of emulating MSX versus owning dedicated hardware. The open-source nature and FPGA implementation were praised. There was some discussion about potential use cases like introducing younger generations to retro computing or connecting to CRT televisions for an authentic experience. The lack of a built-in keyboard was also noted.
The "R1 Computer Use" document outlines strict computer usage guidelines for a specific group (likely employees). It prohibits personal use, unauthorized software installation, and accessing inappropriate content. All computer activity is subject to monitoring and logging. Users are responsible for keeping their accounts secure and reporting any suspicious activity. The policy emphasizes the importance of respecting intellectual property and adhering to licensing agreements. Deviation from these rules may result in disciplinary action.
Hacker News commenters on the "R1 Computer Use" post largely focused on the impracticality of the system for modern usage. Several pointed out the extremely slow speed and limited storage, making it unsuitable for anything beyond very basic tasks. Some appreciated the historical context and the demonstration of early computing, while others questioned the value of emulating such a limited system. The discussion also touched upon the challenges of preserving old software and hardware, with commenters noting the difficulty in finding working components and the expertise required to maintain these systems. A few expressed interest in the educational aspects, suggesting its potential use for teaching about the history of computing or demonstrating fundamental computer concepts.

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.
