Hardware

The PC-9801 UR was a model in the compact "U-line", it had a built in Sound Board, only 2 expansion slot and 3½-inch floppy disk drives like its predecessors, but unlike all other desktop models, it uses the same processor as the notebook PC-9801 NV: the the V30HL/µPD70116H. This processor change would extend to the PC-9801 UF that was released at the same time.
