Cringle's Yaze Z80 emulator. It is a retrocomputing package for running CP/M-style Z80 environments on Unix-like hosts, with attention to accurate CPU emulation, CP/M 3/ZPM3 support, and host-to-emulator file transfer. ### Project history 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. ### Adoption history 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. ### How it is used 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. ### Why package nerds care 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. ### Timeline - 1995: Yaze 1.00 appears as Frank D. Cringle's Yet Another Z80 Emulator. - After yaze 1.10: Andreas Gerlich's YAZE-AG continues the emulator as a 2.x line. - 2.x line: YAZE-AG adds an emulated MMU and BIOS support for CP/M 3.1 or ZPM3. - 2022: The README date for yaze-ag 2.51.3 describes it as a stable final release. ### Related projects - Yaze 1.x is the original emulator line that YAZE-AG continues. - ZPM3 is the CP/M 3-compatible BDOS replacement used by YAZE-AG. - z80pack is another Z80/CP/M emulator suite often mentioned in the same retrocomputing niche. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** yaze-ag - **Version Scheme:** 0 - **Revision:** 0 - **Conflicts With:** cpm - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Game and emulation packages](https://www.automicvault.com/pkg/game-emulation-tools/) - Matched game or emulation metadata. - [Homebrew utility packages](https://www.automicvault.com/pkg/brew-utility-packages/) - Matched Homebrew package provider. - [open-simh](https://www.automicvault.com/pkg/brew/open-simh/) - Shares av.db curated category or tags: cli, emulator, retrocomputing, system. - [cpmtools](https://www.automicvault.com/pkg/brew/cpmtools/) - Shares av.db curated category or tags: cli, retrocomputing, system. - [foot](https://www.automicvault.com/pkg/brew/foot/) - Shares av.db curated category or tags: cli, emulator, system. - [hercules](https://www.automicvault.com/pkg/brew/hercules/) - Shares av.db curated category or tags: cli, emulator, system. - [lzsa](https://www.automicvault.com/pkg/brew/lzsa/) - Shares av.db curated category or tags: cli, retrocomputing, system. - [qemu](https://www.automicvault.com/pkg/brew/qemu/) - Shares av.db curated category or tags: cli, emulator, system. - [rvvm](https://www.automicvault.com/pkg/brew/rvvm/) - Shares av.db curated category or tags: cli, emulator, system. - [abduco](https://www.automicvault.com/pkg/brew/abduco/) - Shares av.db curated category or tags: cli, system. ## Combined YAML source View the package source record on GitHub.
