16 surfaces, 512 tracks/surface, 512 sectors/track, 1 kb/sector, rotation speed 3000 rpm. The disk is operated in cycle stealing mode whereby whenever one byte word is ready it is sent to memory; similarly, for writing, the disk interface reads a 4 byte word from the memory in each dma cycle. Memory cycle time is 40 nsec. The maximum percentage
