In a move to shrink the size of its mainframe computer without sacrificing power, NCR Corp. Has taken advantage of a VLSI chip set, including a proprietary 32-bit CPU, to develop a compact mainframe that comprises only four boards. The modular 9300 system-containing a processor board, a link-level communications card, and two 2-mbyte memory board-lowers heat and power dissipation by a factor of 10 over its 35-board predecessor.
