2. Fixed DM contents, the ID Controller Setup, the user program, and the

instructions table can all be saved to and loaded from a Memory Cassette as

a single unit.

The UM area stores the user’s program. UM area contents can be read and writ

ten only as program data, and not as words. The UM Area can contain up to 3.2K
