Abstract: A computer monitoring apparatus for use with a computer system having a plurality of components interconnected by a system bus is provided to display system information related to the components and data information being transferred through the system bus, and comprises a controller for generating an operation inhibiting signal and a plurality of control signals in accordance with a function selection signal of a key input section, a buffer for temporally storing the system and data information, and a display section for displaying the system and data information on a screen thereof.

Abstract: A SCSI bus-based mass storage system for automatically setting the addresses of a plurality of disk devices includes a SCSI controller for providing predetermined SCSI address signals including addresses data for each peripheral device, and a SCSI ID input device which receives and stores and forwards the corresponding SCSI address ID to the peripheral devices for setting the SCSI ID of addressable peripheral devices. The SCSI controller includes an N-bit shift register having a serial output for providing the SCSI address signals, and a counter for providing the clock signals. Further, the SCSI ID input device includes a plurality of M-bit shift registers which correspond to the number of addressable peripheral devices, where M corresponds to the number of SCSI ID setting jumpers provided in the peripheral devices. Since a manual jumper setting for the SCSI ID can be avoided, faster and more convenient use of the SCSI devices is possible when one or more SCSI devices are added to the computer system.
