Aiwa Mega-CD (Model Number CSD-G1M)

The Aiwa Mega-CD (model number CSD-G1M) is an officially licensed Mega Drive and Mega-CD combination console that is housed within an Aiwa portable CD player and cassette deck. Interestingly, the system is made up of 2 components – the Aiwa CD player/radio/cassette deck and a base that houses the Mega Drive functionality. The CD player/radio/cassette deck system is mounted on top of the Mega Drive base and to function as one unit they must be connected with a patch cable that is included with the system. Also included with the system is an Aiwa-branded 3 button Mega Drive controller molded in blue plastic. The Aiwa Mega-CD only released in Japan during 1994 and is one of the rarest pieces of official Mega Drive/Mega-CD hardware available. There are no reported sales figures for the system.
