A typical minicomputer may have predefined addressable storage, such as 64K X 18 bits, and may require more than that. A technique is described for adding electronics to the storage cards to allow for paging using an input/output (I/O) command set. With such an arrangement, cycle steal may occur to any page regardless of what page the central processing unit (CPU) is using, and provision is made for each I/O unit to have its own paging register.
