NEC Acos System 430

As a mid-size machine, the S430 was announced as the successor of the ACOS System 350 in February 1984. The S430 used 256 kilobit DRAMs for the main memory unit, 16,000 gate CMOS custom LSIs for the central processing unit, and was equipped with a 4,400 gate CMOS gate arrays and other high density logic LSIs employing CMOS technology. Thus it had expanded functionality, and also achieved smaller size, higher speed, lower power consumption, and higher reliability.
