Abstract

A computer system having a CPU, a memory subcircuit, a peripheral subcircuit, a primary SCSI controller, which generates a SCSI bus, a coprocessor, and a secondary SCSI controller, also attached to the SCSI bus. These components are operatively connected in such a way that the coprocessor can access the SCSI bus through the secondary SCSI controller without interfering with the CPU's ability either to run a program from the memory subcircuit or to receive data and control input from the peripheral subcircuit.
