This simple design, possible because the data obeys strict LIFO order, means that no complex data structure is needed to track stack contents - a simple pointer to the top of the stack will do.

For example, a (trivial) new command called hari could be defined that would display one line of memory starting at address 0xc000000, display the contents of the registers, and dump the stack.
