serialNumbers.txt

So whilst there seems to be an issue sorting out the source code, I found a stuffit archive inside the NS Basic 4 source folder which contained the NewtCard source which wasn't corrupt (hooray!)

Inside there I searched the source for "serial" and found the routine to check it: (x-10000017)%127=0

I generated my own serial number by choosing a number, 20, multiplying it by 127 and adding 10000017, which gave me 10002557.

And that serial, amazingly, works in both NewtCard and NS Basic to make the app work :) 

Here are 20 serial numbers generated using this method:
