Why doesn't music gear look like this anymore? This is a Movement Drum Computer, a very rare British-made machine from the very early 1980s. It used analog and digital modules, so could sound like a Linn or a Simmons. It's most prominent owner was Dave Stewart, who used it on 'Sweet Dreams'. Mick Karn from Japan had one, as did Vince Clarke. It's possible that the Chemical Brothers may have one now (link).
