This paper presents a new architecture of push-down stack which is implemented by putting some hardware to a minicomputer HITAC 1O interface. The major advantage of this stack is that it is not a last-in-first-out buffer, Which is useful for recursive programming, backtracking, coroutines, and multiprocessing. In order to make it possible, the top four cells are constructed with accessible registers. The lower portion of the stack is layed in the successive location of main memory. Both overflow and underflow of data from the specified portion of main memory are detected automatically as interrupts, so that it is possible to make the software routine independently which can save or unsave some blocks of the stack in the memory to/from the secondary memory. The method for saving and unsaving is also described.
