Unexpected Arrival: Z80’s New OS Launches in 2026
Scott Baker has introduced an innovative operating system called NostOS, specifically designed for the Z80-based RC2014 homebrew retrocomputer. While some may argue that the Z80 doesn’t need another OS, Baker believes otherwise and has crafted a unique platform from the ground up.
Overview of NostOS
NostOS has been described as having similarities to CP/M but is entirely incompatible with it. This new OS boasts various features that set it apart from older systems.
Core Features
- ROMMable Design: NostOS operates from read-only memory and fits within a 64kB constraint.
- Memory Banking: It supports memory banking, allowing it to exceed the traditional 16-bit limitations.
- Device Compatibility: The system natively supports common serial devices and integrates with the WD37C65 floppy controller.
- Storage Options: Users can incorporate compact flash cards or even Intel Bubble Memory, a technology favored by Baker.
- Display Support: NostOS includes drivers for vacuum fluorescent displays, reviving a once-popular technology.
- Text-to-Speech Capabilities: It features an implementation of text-to-speech using the SP0256A-AL2 chip, enabling unique applications like a talking version of Zork.
Open Source Accessibility
NostOS is an open-source project, with its code available on Baker’s GitHub. This transparency allows users to explore its features and contribute to its development.
The documentation accompanying the OS is comprehensive and user-friendly, ensuring that even beginners can navigate the system effectively.
Potential for Broader Use
Baker has indicated that NostOS is not limited to Zilog’s architecture. It may also operate on hardware like the Intel 8080, broadening its usability.
In conclusion, NostOS marks a significant addition to the Z80 ecosystem, offering novel features and capabilities that could rejuvenate interest in retrocomputing. Scott Baker’s passion for legacy technology shines through in this exciting new operating system.
