NewtCard-for-Newton-OS
It's a miracle this even exists.
The experience of resurrecting this software is similar to the odyssey of Mason Mark, detailed here.
Feel free to look at the code, try to run it and have fun.
Go ahead and open issues - I won't be fixing any of them. Seriously, it's 25 years since I've looked at the source. I have no idea how to get the Newton Toolkit running - you'll need that to compile it.
There are a number of documents with no extension. These are probably in WordPerfect format.
NewtCard was released in 1997. Development ended with the cancellation of the Newton in 1998. During its short life, it won all the major software awards for Newton OS software.
