Development

NEC-HE was a subsidiary company of NEC and manufacturer of consumer electronics. In 1980, they started manufacturing the PC-8001 which was developed by the Electronic Devices division of NEC. 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 division developed the PC-8801 for home and business, and the Information Systems division developed the PC-9801 for business. In 1983, NEC had four personal computer lines come out from different divisions. To avoid confliction, they decided to consolidate personal computer business into two divisions; NEC-HE dealt with the 8-bit home computer line, and the Information Systems division dealt with the 16-bit personal computer line. NEC-HE discontinued development of the PC-6000 series, the PC-6600 series, and the PC-8000 series. They were merged to the PC-8800 series.[2]

gollark: For efficiency.
gollark: Modern shuffle implementations just do bogosort with a patched List type which throws an immediately-caught exception upon one round of sorting being completed.
gollark: Of course.
