Its GitLab project was created in February 2019, consistent with a later public hosting home for a longer-lived simulator codebase. ### Adoption history DPS8M's adoption is primarily in retrocomputing, operating-system preservation, and Multics study rather than ordinary application development. Packaging in Homebrew and Nix gives users a repeatable way to install a simulator that would otherwise live mostly in source builds and specialist documentation. ### How it is used Users build or install the simulator, then run dps8 and companion utilities such as tape and printer conversion tools. The official documentation is aimed at end users, operators, developers, and package maintainers, covering installation, compilation, configuration, operation, and troubleshooting. ### Why package nerds care For package nerds, DPS8M is interesting because it packages a historically specific mainframe simulator with multiple utilities, generated cross-reference documentation, and release-specific omnibus manuals, tying modern Unix package management to preserved 36-bit computing environments. ### Timeline - 2006: the project README's copyright range begins, indicating the long-running development team history. - 2016: early alpha and release-candidate tags were present in the GitLab tag history. - 2019: the GitLab project record was created. - 2025: official documentation listed release-specific manuals for R3.0.0, R3.0.1, and R3.1.0. ### Related projects - Multics - SIMH - GE-645 - Honeywell 6180 - Bull DPS-8/M ### 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:** dps8m - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - dps8m: normalized package name match | nixpkgs package indexes: pkgs/by-name/dp/dps8m/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Related links - [Terminal utility packages](https://pkg.so/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://pkg.so/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Game and emulation packages](https://pkg.so/game-emulation-tools/) - Matched game or emulation metadata. - [Homebrew utility packages](https://pkg.so/brew-utility-packages/) - Matched Homebrew package provider. - [llvm](https://pkg.so/brew/llvm/) - Build dependency declared by Homebrew. - [lld](https://pkg.so/brew/lld/) - Build dependency declared by Homebrew. - [open-simh](https://pkg.so/brew/open-simh/) - Shares pkgdb curated category or tags: cli, emulation, emulator, retrocomputing, simulator. - [qemu](https://pkg.so/brew/qemu/) - Shares pkgdb curated category or tags: cli, emulation, emulator, system. - [hercules](https://pkg.so/brew/hercules/) - Shares pkgdb curated category or tags: cli, emulator, mainframe, system. - [yaze-ag](https://pkg.so/brew/yaze-ag/) - Shares pkgdb curated category or tags: cli, emulator, retrocomputing, system. - [bochs](https://pkg.so/brew/bochs/) - Shares pkgdb curated category or tags: cli, emulator, system. - [foot](https://pkg.so/brew/foot/) - Shares pkgdb curated category or tags: cli, emulator, system. - [cpmtools](https://pkg.so/brew/cpmtools/) - Shares pkgdb curated category or tags: cli, retrocomputing, system. - [rvvm](https://pkg.so/brew/rvvm/) - Shares pkgdb curated category or tags: cli, emulator, system. ## Combined YAML source View the package source record on GitHub.
