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.
