+The NEC TK 80 is a 8080-cpu Training Kit (hence the "TK") computer sold at the end of the 70's. It is considered the first japanese home-computer. It was firstly aimed at technicians, but it met a great success with first computer hobbyists. It was often sold as a kit.
+
+The systems is directly programmed in machine-code through the hexadecimal keyboard. There are 9 "function" keys on this keyboard : RET, RUN, STORE DATA, LOAD DATA, RESET, ADRS SET, READ INCR, READ DECR, WRITE INCR.\
+Information is displayed on the built-in 7-segments LED display (1 line, 8 characters).
+
+The **TK-80E** is low-cost TK-80. The CPU and some chips are slightly different (uPD8080AD -> uPD8080AFC, uPD8228D -> uPD8228C, uPD454D -> uPD464C, uPD5101E -> uPD2101AL-4), thus reducing the production cost (ceramic -> plastic). Of course the TK-80E was less expensive.
+
+The **TK-80 BS** was a "Basic Station" model. It was composed of a TK-80 board with a BASIC ROM built-in, 7k RAM and an alphanumeric keyboard. Furthermore there was the [Compo BS/80](/museum/nec-compo-bs-80/) which was a TK-80 with its Basic extension within a nice moulded plastic case.
+
+The TK-80 was used as a base for the [PC-8001](/museum/nec-pc-8001/), the [PC-8801](/museum/nec-pc-8801/) and the [PC-9801](/museum/nec-pc-9801-e/).
