Voodoo Reborn: 3DFX GPU Recreated in FPGA

Francisco Ayala Le Brun has recreated the 3DFX Voodoo 1 GPU in SpinalHDL for FPGAs, detailing the fixed-function hardware architecture and the timing/bug challenges of mapping a classic GPU onto modern programmable logic, with a GitHub repository for curious readers; the piece nods to Nvidia’s late-90s acquisition of 3DFX and notes the option of upgrading real Voodoo memory for those who own original hardware.

DR-DOS Returns as a Clean-Room 9.0 Beta

A Reddit user has created a clean-room reimplementation of DR-DOS, calling it version 9.0 and placing it in beta after purchasing the trademark. The project aims for full compatibility with DOS, currently runs DOOM, and is free for non-commercial use for now, though the author has not open-sourced the code due to IP/licensing considerations tied to DR-DOS' history with Novell and Caldera.

Windows 98 in 2026: Nostalgia Meets Modern Web Realities

A Hackaday retrospective tests Windows 98 SE on a Dell Dimension 2100 in 2026, finding it workable for basic office tasks and some 2000s-era software, but modern internet use is painful due to TLS and browser support, often requiring proxies or plugins; gaming is limited to era-appropriate titles; overall, it's a nostalgic curiosity rather than a viable daily driver.

DIIS: A 1990s Hybrid Upgrade for Chornobyl NPP

In the 1990s, the Chornobyl Nuclear Power Plant modernized its remaining RBMK reactors not by a full rebuild of the Soviet-era mainframe, but by wrapping a new auxiliary information-measurement system (DIIS) around the 1970s SKALA mainframe. The upgrade linked a Ukrainian SM-1210 minicomputer and an ARCnet-connected 80386 PC to run real-time reactor-core modeling and visualization via the PRIZMA program, letting data stay local instead of being sent to Moscow. Unit 2 operated until 1991 (turbine fire), Unit 1 until 1996, and Unit 3 until 2000, yielding a pragmatic, hybrid upgrade that pushed the plant toward 21st-century capabilities.

Windows 98 Gets a Second Life on a 2020 ThinkPad With UEFI-CSM and Adapters

A 2020 ThinkPad P14s Gen 1 can run Windows 98 SE alongside Windows 11 and Linux from the same NVMe drive by booting in UEFI-CSM mode and using a USB‑2.0 expansion chain via Thunderbolt to compensate for Win98’s drivers. The setup requires disabling Secure Boot, enabling CSM, and using workarounds like the CREGFIX DOS driver and Rudolph Loew RAM patch to bypass 512 MB RAM limits; ACPI is faked with a S3 power state, and graphics are limited to basic VESA due to lack of Win98 drivers. Disk access goes through BIOS rather than NVMe, but overall the experiment demonstrates surprising backward compatibility on modern hardware.

Mid-'90s Macs' Upside-Down Capacitor Mystery Unveiled by Hobbyists

Hobbyists have discovered that a capacitor in the mid-90s Macintosh LC III was installed incorrectly, likely due to a design oversight by Apple. This issue went largely unnoticed because the capacitor's function was limited and it was initially rated to handle the voltage. Hobbyists like Brown are now warning others to install the capacitor correctly during repairs to avoid damage. Modern restorers often use tantalum capacitors, which are more sensitive to incorrect voltage. A reverse-engineered schematic is available for those needing to replace damaged boards.

1993 ThinkPad Tablet Restored to Former Glory

A retrocomputing enthusiast, [polymatt], successfully restored a severely damaged 1993 IBM ThinkPad Tablet. Despite its cracked LCD screen and battered case, [polymatt] managed to find a compatible replacement screen and undertook extensive repairs, including recapping, recabling, and fixing the batteries. This restoration highlights the value and challenge of reviving rare vintage technology.

"Reviving the Legacy of the Jupiter ACE Computer"

Enthusiasts Cees Meijer and Scott Baker have recreated the rare 1982 Jupiter ACE computer, which was notable for running Forth instead of more popular languages of the time. The original ACE, resembling the Sinclair ZX81 and developed by former Sinclair employees, suffered from production issues and sold poorly. Meijer's replica, based on Grant Searle's design with some modifications, features a 3D printed keyboard that mimics the original's aesthetic. This project highlights the continued interest in vintage computing and the DIY spirit within the retro tech community.

Retro-style laptop with 8088 CPU and 640KB RAM now available for $200.

The "Book 8088" laptop, available on AliExpress, combines modern components with an Intel 8088 processor and 640KB of memory to recreate the experience of using an original IBM PC from 1981. The laptop features a 640x200 16-color LCD screen and built-in interfaces that allow USB accessories and CompactFlash cards to interface with the ancient components. The slow speed and low memory limit make it best suited to MS-DOS, with its text-based interface and general lack of multitasking support. The laptop is made by Hong Kong-based manufacturer Xinrui Technology and is sold out in most versions.
