General 
4.01 A block diagram of the SX-2OOe DIGITAL configuration (five 
bays) is shown in Figure 4-1. Figure 4-2 shows a block diagram 
of the SX-200@ DIGITAL 336-port configuration (four digital bays). The 
heart of the system is the Main Controller, a l6-bit microprocessor 
operating at a clock frequency of 8 megatlertz. The Main Controller, 
through its address, data, and control buses, interfaces to a floppy disk 
unit, memory, Direct Memory Access...
