New Nippon Electric (新日本電気, Shin Nippon Denki) was a subsidiary of NEC and a manufacturer of consumer electronics. They started manufacturing the PC-8001 and its peripherals which were developed by the Electronic Devices Group of Nippon Electric. It was successful and grew the personal computer market in Japan.
They started developing a low-cost home computer, and it became the PC-6001. At the same time, the Electronic Devices Group developed the PC-8801 for home and business, and the Information Processing Group developed the PC-9801 for business market.
In 1983, New Nippon Electric changed its name to NEC Home Electronics. At that time, NEC group had four personal computer lines come out from different divisions. To avoid conflict, they decided to consolidate personal computer business into two divisions; NEC Home Electronics dealt with the 8-bit home computer line, and the Information Processing Group dealt with the 16-bit personal computer line.
NEC Home Electronics discontinued development of the PC-6000 series, the PC-6600 series, and the PC-8000 series. These lines were merged to the PC-8800 series.[5]
