The actual C++ source code can be found here:

The Newton doesn't use standard DES. The difference can be found in UDES::CreateKey function, i.e. in key scheduling. Indeed, this function has a special argument to generate the key according to the Newton implementation (or according to the standard). I believe they meant to implement standard DES, but failed to do so and since the same source code was used on the Newton, on the Mac and on Windows, they never realized or realized too late about this bug.
