Description
In July 1987, NEC marketed a compact general-purpose small machine called the ACOS System 3300 (hereafter referred to as the S3300) as the successor of the ACOS System 410. The S3300 achieved a smaller size by employing CMOS throughout -- using fully-custom CMOS LSI with 30,000 gates per chip for the arithmetic processor (EPU), and CMOS VLSI in input-output processors and peripheral control processors -- and employing 3-dimensional mounting based on surface-mounted and double-sided mounted SIMs (Single Inline Modules) for 1-megabit DRAM chips in the main memory unit.
