NostOS Emerges: A ROM-Based Z80 OS for RC2014
Scott Baker has created NostOS, a brand-new ROM-only operating system for the Z80-based RC2014 retrocomputer. Described as CP/M-like but not compatible with CP/M, NostOS fits in 64KB of ROM with banking to extend memory, and includes native support for serial devices, the WD37C65 floppy controller, compact flash, and even Intel Bubble Memory, plus a text-to-speech feature and a Zork port; the project is open-source on GitHub.
