NEC μCOM Series
The NEC μCOM series is a series of microprocessors and microcontrollers manufactured by NEC in the 1970s and 1980s. The initial entries in the series were custom-designed 4 and 16-bit designs, but later models in the series were mostly based on the Intel 8080 and Zilog Z80 8-bit designs, and later, the Intel 8086 16-bit design. Most of the line was replaced in 1984 by the NEC V20, an Intel 8088 clone. Overview The μCOM series has its roots in one of the world's earliest microprocessor chipsets, the two-chip processor μPD707 / μPD708. Early in 1970, Coca Cola Japan set out to increase the efficiency of their sales outlets by introducing new POS terminals. Sharp Corporation, Sharp was contracted to build these terminals, and NEC in turn to develop a chipset. The chipset development was complete in December 1971, at about the same time as other early microprocessors in the USA. Since then, NEC has developed and manufactured various microprocessors and microcontrollers. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ZX80
The Sinclair ZX80 is a home computer launched on 29 January 1980 by Science of Cambridge Ltd. (later to be better known as Sinclair Research). It is notable for being one of the first computers available in the United Kingdom for less than a hundred pounds. It was available in kit form for £79.95, where purchasers had to assemble and solder it together, and as a ready-built version at £99.95. The ZX80 was advertised as the first personal computer for under £100 and received praise for its value and documentation. However, it faced criticism for screen blanking during program execution, small RAM size, and the keyboard design. It was very popular straight away, and for some time there was a waiting list of several months for either version of the machine.

TK-80
The TK-80 (μCOM Training Kit TK-80) was an 8080-based single-board computer kit developed by Nippon Electric Company (NEC) in 1976. It was originally developed for engineers who considered using the '' μCOM-80 family'' in their product. It was successful among hobbyists in late 1970s in Japan, due to its reasonable price and an expensive computer terminal not being required. History NEC started as a telecommunications equipment vendor, and their business was heavily dependent on Nippon Telegraph and Telephone Public Corporation (NTT). To increase private demand and exports, NEC began developing new industries such as computers and semiconductors in the 1950s. Although those businesses were not profitable enough, NEC continued investing profits from successful telecommunication business. In the 1970s, the Semiconductor Division developed several microprocessors including Intel compatible processors, and in 1976 got a second-source agreement with Intel to produce the 8080 mi ...
