Gershwin

At the same time as Copland was being prepared, Apple Inc. was busy working on the successor project for Copland, named Gerschwin.

The major problem Gerschwin would resolve would be the memory issue. Copland would have made pre-emptive multitasking a reality -- to an extent, with the leftover bits given instead to Gerschwin.

Gerschwin was "killed" at the same time (if not earlier) Copland was cancelled.
