JS99'er

This is the 'new' version of js99er.net developed using Angular and TypeScript. Try it here.

This project was originally generated with Angular CLI version 1.7.3 (currently 18.2.7).

Setting up the development environment

• Clone the repository to a folder on your computer
• Install Node.js
• Install Angular CLI: npm install -g @angular/cli
• Change to the directory containing the source code and install the dependencies: npm install
• Run js99er locally by typing: ng serve
• Open a browser and enter the address: http://localhost:4200

Development server

Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Build

Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the --configuration production flag for a production build.

Embedding into a website

First build the project. Then edit the dist/index.html file and insert a config attribute into the js99er element, e.g.:

<js99er config='{"sidePanelVisible": false, "toolbarVisible": false, "cartridgeURL": "my-folder/my-cart.rpk", "diskURL": "", "ramDiskDSRURL": "", settings": {}}'></js99er>

The config attribute is formatted as a JSON object. Setting both sidePanelVisible and toolbarVisible to false will disable the JS99er UI, leaving only the console canvas.

Note: in the example above, my-folder must be a subfolder to the assets folder.

The settings object may contain the following properties, shown here with the defaults (note: don't include line breaks or comments in the settings attribute):

"settings": {
    "enableSound": true,
    "psg": "STANDARD",              // "STANDARD" | "FORTI"
    "enableSpeech": true,
    "ram": "32K",                   // "NONE" | "32K" | "SAMS1M" | "SAMS4M" | "SAMS16M"
    "vdp": "TMS9918A",              // "TMS9918A" | "F18A" | "V9938"
    "enablePCKeyboard": false,
    "enableMapArrowKeys": false,
    "enableGoogleDrive": false,
    "enableGRAM": false,
    "enablePixelated": false,
    "enablePauseOnFocusLost": false,
    "tipi": "NONE",                 // "NONE" | "MOUSE" | "FULL"
    "tipiWebsocketURI": "ws://localhost:9901/tipi",
    "enableDebugReset": false,
    "enableH264Codec": false,
    "enableDisk": true,
    "enablePCode": false,
    "ramDisk": "NONE"               // "NONE" | "HORIZON"
}

URL parameters

By including URL query parameters, the emulator can load a specific cartridge and/or disk on startup:

cartUrl Load a cartridge image. This can either be a full URL or a URL relative to the assets folder. The program on menu item 2 in the cartridge will open automatically.

diskUrl Load a disk image. This can either be a full URL or a URL relative to the assets folder.

Example: https://js99er.net/#/?cartUrl=software/turboforth.rpk&diskUrl=software/turboforth.dsk

Note: The alternative way of loading a cartridge https://js99er.net/#/?cart=Parsec still works, but is likely to be removed in a future version.
