プロジェクトの歴史

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.

採用の歴史

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.

使われ方

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.

パッケージ好きにとっての重要性

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.
