You don't have to pay for these old apps anymore. If you are still tinkering with the Newton OS, that's awesome and you should feel free to use Five Speed's apps free of charge. Just install the registration code generator on your Newton device (real or emulated) and you can generate a registration code that will fully unlock any of Five Speed's formerly-commercial Newton apps.
Enter your Newton user name in the box, select which product you want a code for, and then press the "Generate SN" button.
😬NOTE: If you are easily offended, please do not try to generate a code without entering the user name. This was strictly an internal tool back in the 1990s and so the error messages are... not polite.
Have fun!
