The COMPO-BS/80 is a "personal computer" based on the TK-80BS, manufactured to provide hobbyist with an out of box functioning BASIC machine. The release of the COMPO-BS/80 was followed by the release of the PC-8001, NEC's first true personal computer.
Hardware
The COMPO-BS/80 is basically a TK-80BS with more RAM, a CPU and a case. It does not use a TK-80/E board, instead it uses a different dedicated CPU board for the μPD8080A chip which it attaches to the built in TK-80BS.
The COMPO-BS/80 was released in two versions: The COMPO-BS/80-A, which came with a built in cassette deck. And the COMPO-BS/80-B, which lacked said cassette deck, but could be used alongside an external one.
The components of the COMPO-BS/80 were also sold individually, including the case, allowing owners of a TK-80/E to build their own COMPO-BS/80, this build doesn't allow for BASIC access from start-up, instead needing access to the TK-80/E's keypad for it. Alongside selling components, the COMPO-BS/80 had dedicated peripherals and expansion units that were marketed for it, and it was also compatible with older components such as the TK-M20K.
