CSD-G1M

Probably the most unusual of any incarnation of the Mega Drive was a variant, the Aiwa Mega CD, built around an Aiwa CD player. The unit was made up of two components - an Aiwa bookshelf-size CD radio and a dock which added the Mega Drive connections (excepting sound, which the main radio unit handled.) Oddly, Sega and Aiwa chose not to place the interface between the two on the sides that would connect, but instead opted to use a connection cable on the back. This variant of the Mega Drive is one of the rarest made, and only saw limited release into the Japanese and European markets.
