This little slice of retro boombox goodness is the Sharp MR-990, not just a boombox, but a boombox witha built-in “detachable keyboard computer capable of piano and rhythm functions.”
It was released in 1985, at a price of $550, and featured a 5-band graphic equalizer, detachable speakers and the “melody computer.”
