A YouTuber known as MINT spent three months hand‑soldering old memory chips and 8‑bit logic components to create EPROMINT, a complete CPU with its own ALU, memory controller, I/O, interrupt system and a VFD display capable of playing low‑resolution video, and released all designs as open‑source on GitHub.
Microsoft has finally released the source code of its 1976 6502 BASIC interpreter under an open‑source license, a historic move that revives the early programming language that ran on Apple II, Atari 2600, NES and Commodore 8‑bit machines, and invites enthusiasts to explore and rebuild the original environment.
A YouTuber known as MINT documented the creation of EPROMINT, a complete 8‑bit CPU built from discarded memory chips and simple logic components, detailing its ALU design, modular architecture, custom instruction set, interrupt handling, video output, open‑source release, and plans for a C compiler.
This article explores why early 1980s games such as Contra could deliver rich graphics, music, and gameplay within just 128KB of memory, explaining tile‑based rendering, limited audio chip capabilities, and ultra‑compact code techniques that made such feats possible.
SvarDOS is a newly independent open‑source DOS distribution that fits on a floppy, supports networking, runs classic software like MS Word 6, and offers a modern package manager with online updates, making retro computing on virtual machines and old hardware both practical and enjoyable.
This article details how a developer rebuilt the original Macintosh 128K using a low‑cost RP2040 microcontroller, covering the hardware design for VGA output, the software stack built around the Musashi 68‑bit emulator, performance‑tuning tricks, and the remaining limitations such as running MacPaint.
An anonymous developer built WinGPT, a C‑based ChatGPT client that runs on Windows 3.1 and later 16‑or 32‑bit Windows versions, using native TLS 1.3 to connect to OpenAI’s API, highlighting the challenges of retro UI controls, Winsock dependency, and icon creation on legacy systems.
This article presents the complete assembly source of the RAMinit TSR program written by Lei in 1994, explains its purpose as a hot‑key‑driven memory‑management utility for DOS, describes its interrupt‑vector handling, memory‑copy routines, and includes detailed comments that reveal the inner workings of this historic piece of system software.
