Newton Bowels Project
One of the major problems of NewtonOS is that Apple documentation isn't complete. The first reason is that
the C++ tools were published lately and they are derived from the system sources. Consequently, many APIs that
are required for some software, are unavailable.
Another reason is that, as usual, there is a non documented part reserved for future versions of the OS.
Before Apple releases NewtonOS 3, it seems useful to document everything we find and to show how the
system works.
This idea is the root of the Newton Bowels project (so called because of the
BowelsOfTheMemoryMgr).
It is about sharing sample codes, tools, documenting system functions, explain some mechanisms.
I host, besides the papers and the tools I wrote, everything I've been sent for that project.
Don't hesitate to send me papers to add them to the list below.
