Last week, electronics engineer Lorentio Brodesco announced the completion of a mock-up for nsOne, reportedly the first custom PlayStation 1 motherboard created outside of Sony in the console's 30-year history. The fully functional board accepts original PlayStation 1 chips and fits directly into the original console case, marking a milestone in reverse-engineering for the classic console released in 1994.

Brodesco's motherboard isn't an emulator or FPGA-based re-creation—it's a genuine circuit board designed to work with authentic PlayStation 1 components, including the CPU, GPU, SPU, RAM, oscillators, and voltage regulators. The board represents over a year of reverse-engineering work that began in March 2024 when Brodesco discovered incomplete documentation while repairing a PlayStation 1.

"This isn't an emulator. It's not an FPGA. It's not a modern replica," Brodesco wrote in a Reddit post about the project. "It's a real motherboard, compatible with the original PS1 chips."

On Tuesday, classic computer collector Joe Strosnider announced the availability of a new 3D-printer filament that replicates the iconic "Platinum" color scheme used in classic Macintosh computers from the late 1980s through the 1990s. The PLA filament (PLA is short for polylactic acid) allows hobbyists to 3D-print nostalgic novelties, replacement parts, and accessories that match the original color of vintage Apple computers.

Hobbyists commonly feed this type of filament into commercial desktop 3D printers, which heat the plastic and extrude it in a computer-controlled way to fabricate new plastic parts.

The Platinum color, which Apple used in its desktop and portable computer lines starting with the Apple IIgs in 1986, has become synonymous with a distinctive era of classic Macintosh aesthetic. Over time, original Macintosh plastics have become brittle and discolored with age, so matching the "original" color can be a somewhat challenging and subjective experience.

We're used to updating Windows, macOS, and Linux systems at least once a month (and usually more), but people with ancient DOS-based PCs still get to join in the fun every once in a while. Over the weekend, the team that maintains FreeDOS officially released version 1.4 of the operating system, containing a list of fixes and updates that have been in the works since the last time a stable update was released in 2022.

FreeDOS creator and maintainer Jim Hall goes into more detail about the FreeDOS 1.4 changes here, and full release notes for the changes are here. The release has "a focus on stability" and includes an updated installer, new versions of common tools like fdisk, and format and the edlin text editor. The release also includes updated HTML Help files.

Hall talked with Ars about several of these changes when we interviewed him about FreeDOS in 2024. The team issued the first release candidate for FreeDOS 1.4 back in January.
