DOSee

   

If you enjoy DOSee, consider buying me a cup of coffee?

An MS-DOS emulator for the web.

DOSee is a front-end for an MS-DOS emulation ecosystem to use on the web. The text-based MS-DOS was the dominant personal computer platform for much of the 1980s. Up until the mid-1990s before being superseded by Microsoft Windows. Emulating this platform allows tens of thousands of games, demos and applications from this era to run on a web browser both online or offline as a desktop web-app!

DOSee is only a user interface and installation process for an incredible emulation ecosystem. Many remarkable people created it over many years. DOSee itself is a fork of The Emularity project started by the Internet Archive. EM-DOSBox, the core of this emulation, is a JavaScript port of DOSBox, the world's most popular MS-DOS emulator.

What's new

Updates are in CHANGES

Requirements

• A web browser that supports service workers.
  Current Chrome, Edge, Safari, or Firefox will work fine.
• A physical keyboard, as MS-DOS is a text-based operating system.
• Node.js or Docker

DOSee runs over an HTTP server, and it can not function over the file:/// browser protocol.

Instructions, download, build and serve

DOSee requires a build before it can serve to a web browser.

# clone DOSee
git clone git@github.com:bengarrett/DOSee.git
cd DOSee

 # install dependencies & build
npm install # (or the equivalent in another package manager)

# serve DOSee over port 8086
npm run serve

Point a web browser to http://localhost:8086

Are in the USAGE document

Editing the source JS or HTML

If you edit the source files in src/ you will need to rebuild the application.

# change to the repo directory
cd DOSee

# re-build DOSee using your edits
npm run install

# serve the modified DOSee over port 8086
npm run serve

Point a web browser to http://localhost:8086

Due to the PWA offline feature, web browsers need to unregister the service workers to reflect any changes to the application code. There is a red Update DOSee and the service worker button on the index.html example that will do this and then reload the browser window. The eventListener code for this button can be found in the src/js/dosee-sw.js file.
