The PC386sx/MC from NCR is an 80386 based PC compatible.
The 386SX processor runs at 20 MHz. It transfers 16-bits of data and processes 32-bits of data at a time.
The Micro Channel-compatible bus is designed for high-speed transfer of data from the microprocessor to peripherals. It permits software configuration of hardware and use of multiple processors called bus masters.
This system is available with a SCSI fixed disk drive. The SCSI connector on the main processor board connects one or two internal disk drives to the SCSI controller.
