To be correct: to use additional RAM for NewtonScript Heap. The
Newton allocated the NS Heap and other fixed size heaps and declares
all the remaining memory as free. If you run some C++ code which
allocates memory, it will be taken from that pool. If you insert a
card with a removable handler, the handler is loaded in a separate
heap which is drawn from that pool, too.

In fact, there was also the Newton, Inc patch (717246). It has the
same functionalities than the 717260, was released few 14 days
earlier, has the same internal version (this allows a patch to refuse
to install if you already have something greater), but patches the
Apple string to Newton Inc. Can't remember its name exactly (for the
naming convention, I put all I guessed into the FAQ).

Those patches introduce other changes to the ROM, such as the
contrast slider tap functionality.

And in prior versions. (the bug is not in the patch but in the ROM)
