This repository implements an online computer museum that provides web-based emulators of historical computer systems. The application integrates multiple emulator backends (DOSBox, PCE, MAME, etc.) through a unified interface called emularity, allowing users to interact with vintage computing systems directly in their browser. The system includes contextual documentation for each emulated machine and features special exhibits like labs and standalone demonstrations. The architecture is client-side heavy, using iframes and canvas elements to display emulator output, with machine-specific configurations loaded via JSON files.
AtoM (Access to Memory) is a mature, open-source web application for archival description and access, developed by Artefactual Systems. In production, it manages hierarchical archival descriptions (fonds, series, files, items), authority records, repositories, digital objects, and accessions. It supports multiple archival standards (EAD, EAC, MODS, METS, Dublin Core) and provides multilingual, multi-repository archival description. The application is built on PHP 7/8 with a Symfony 1.x core, Propel ORM for persistence, and Elasticsearch for search indexing, with MySQL/MariaDB as the primary datastore and Gearman for background job processing.
Vrecord is a bash-based CLI and GUI application for capturing analog and digital video signals to digital files, designed primarily for audiovisual archivists. It wraps ffmpeg-ma (a MediaArea fork of FFmpeg with Blackmagic DeckLink support) to capture from DeckLink devices, DV via FireWire, or audio-only inputs, and provides real-time monitoring through ffplay or mpv with configurable scopes (waveform, vectorscope, histograms, bit planes, etc.). The application generates preservation-oriented sidecar files including frame-level MD5 checksums, SCC closed caption files, QCTools XML reports, timecode logs, and optional access MP4 copies. Post-capture, it runs MediaConch policy checks, generates benchmark graphs with gnuplot, and can embed logs into Matroska containers. The codebase is monolithic, consisting of a single ~5000-line bash script (vrecord) that handles configuration (via gtkdialog), capture pipeline construction, and post-processing. Companion scripts include vtest for test signal output, vplay for playback with QC overlays, and cchex_to_display for real-time closed caption display. Dependencies are managed via Homebrew on macOS and Linux (including the AMIA Open Source tap). The project has been maintained for nearly a decade and is actively developed by a community of archivists and developers.
