NEAC 1240

In February 1967, NEC announced the NEAC-1240�the world's first ultra-small computer using ICs. After the announcement of the NEAC-1201 in 1961, parametron ultra-small computers were outstanding in terms of stability and reliability, but NEC gradually realized their inferiority to transistors in terms of performance, and in 1965 they began development of a high-performance ultra-small machine using ICs (Integrated Circuits) due to the improvement in IC performance. In addition to switching to ICs, the NEAC-1240 was the first computer in this class to use core memory. The performance of the NEAC-1240 was revolutionary for an ultra-small computer at the time.
