Historique du projet

The older yaze documentation shows Yaze 1.00 as a 1995 Z80 emulator by Frank D. Cringle. The YAZE-AG README describes yaze-ag 2.51.3 as a further development of yaze 1.10, maintained by Andreas Gerlich at the University of Ulm.

YAZE-AG's 2.x line added an emulated memory-management unit and a BIOS for CP/M 3.1 or the ZPM3 replacement used by the package. The README also highlights undocumented-opcode support, regression testing against real Z80 hardware, and portability across Solaris, Linux, Raspberry Pi OS, Orange Pi, FreeBSD, macOS, and Cygwin.

Historique d'adoption

The adoption story is narrow but real: YAZE-AG circulates in CP/M and Z80 retrocomputing circles, where users want a Unix-hosted emulator that can boot CP/M-compatible environments and move files between the host and emulated drives. Forum posts and package ports preserve it as a specialist emulator rather than a mainstream virtualization tool.

Modes d'utilisation

Users run yaze to start the Z80/CP/M environment, use bundled disk images or CP/M drive mappings, and use tools such as R.COM, W.COM, or the cdm disk manager to move files between host directories and emulated CP/M storage. The README calls out read-only mounted host directories for importing files into the emulator.

The package is especially useful for experimenting with CP/M utilities, WordStar-era software, Z80 code, and disk images without needing original hardware.

Pourquoi les passionnés de paquets s'y intéressent

YAZE-AG is package-manager archaeology in the best sense: a small C emulator whose value is preserving access to a vanished operating environment. It is significant because package collections make retrocomputing tools reproducible and buildable on current Unix systems.

It also shows a common pattern in emulator packaging: an original project, a maintainer-specific continuation, documentation hosted on a university page, and downstream packages keeping the whole thing installable long after the target machine disappeared from ordinary use.
