That’s my cell phone running the Apple ][ version of Lemonade Stand.
Yes. My cell phone. Running an Apple ][ app.
How?
Pretty easy to use… download, extract, put disk images in the Disks directory, and (on Windows or Mac) run the relevant script, or enter the following command on Linux (taken RIGHT from the Windows CMD file, just with proper slashes instead of backslashes, and cp instead of copy ;)):
java -jar Tools/AppleIIGoPacker.jar
cp AppleIIGo/bin/AppleIIGo.jad AppleIIGo/AppleIIGo.jad
That cp operation isn’t necessary if you use Sprint – and if you do use Sprint, upload it to your phone using Rumkin’s Phone Uploader. (Upload the AppleIIGo.jar (not the jad) file from the AppleIIGo directory.)
Enjoy!
