TL;DR
A new version of the CP/M operating system, named CP/M-386, has been developed for Intel 386 processors operating in protected mode. Derived from CP/M‑68K, this update aims to extend CP/M’s relevance to modern 386-based systems. The development is confirmed, but broader adoption details remain unclear.
CP/M-386 is a new version of the classic operating system designed specifically for Intel 386 processors in protected mode. It is derived from the earlier CP/M‑68K version and aims to bring CP/M’s familiar environment to more advanced hardware. The project’s developers confirmed the release, highlighting its compatibility with 386 hardware and its potential to modernize CP/M’s legacy.
The CP/M-386 operating system has been officially announced by a development team working on extending CP/M’s architecture to current-generation hardware. It is based on the CP/M‑68K design, which was originally created for Motorola 68000-based systems. The new version targets Intel 386 processors operating in protected mode, a feature that allows for advanced memory management and multitasking capabilities not available in earlier versions.
According to the developers, CP/M-386 aims to preserve the familiar command-line interface and application environment of classic CP/M, while leveraging the advanced features of the 386 architecture. The project is still in early development, and it is not yet clear whether it will support existing CP/M software or require new applications to be written specifically for it. The developers emphasized that this is a research and development project intended to explore the possibilities of updating CP/M for modern hardware.
Potential Impact of CP/M-386 on Legacy and Modern Computing
The development of CP/M-386 could have significant implications for the preservation and evolution of legacy operating systems. By adapting CP/M to the Intel 386’s protected mode, it opens the door for running classic CP/M applications on contemporary hardware, potentially bridging older software environments with modern systems. This could benefit vintage computing enthusiasts, software preservation efforts, and educational projects. However, as the project is still in early stages, its practical impact remains uncertain until further development and testing are completed.

Background: From CP/M to Modern Hardware Compatibility
CP/M (Control Program for Microcomputers) was a dominant operating system in the late 1970s and early 1980s, primarily used on 8-bit microcomputers. Its architecture was designed for early microprocessors like the Intel 8080 and Zilog Z80. Over time, as hardware advanced, CP/M was replaced by MS-DOS and other modern operating systems. The CP/M‑68K version was an adaptation for Motorola 68000-based systems, which introduced some new features but remained largely compatible with the original concept.
The Intel 386 processor, introduced in 1985, introduced protected mode, enabling multitasking, virtual memory, and hardware-level security. Until now, CP/M was not adapted for this architecture, which limits its relevance on contemporary hardware. The new CP/M-386 project aims to fill this gap, leveraging the protected mode capabilities of the 386 to modernize CP/M’s architecture and potentially extend its lifespan.
“This project is about exploring how classic CP/M can be adapted to leverage the advanced features of the Intel 386, especially protected mode, to see if it can find a place in modern hardware environments.”
