The TK-80 (Training Kit 80) is a hobbyist microcomputer released in 1976 by NEC. It is considered NEC's first meaningful foray into the home computer market.
Hardware
The TK-80 is a simple device designed to help Japanese consumers learn how to use computers. By default it is merely just a printed circuit board with eight seven segment VFD displays and twenty-five keys, however with expansions it can be given a full stroke keyboard, a cassette loader and can be hooked up to a television to run rudimentary software.
Due to its suprising success, the TK-80 had many later revisions and even copycats, eventually culminating in NEC releasing its first real home computer, the PC-8001.
