Vintage Keio/Korg Rockmate Donca Matic Drum Machine

Description

Up for sale is a vintage Keio Rockmate Donca Matic drum machine.
It's in fairly decent shape for its age and still has the original styrofoam box that it came with.
There's a small bit of rust in the inner corner of the bottom pan and the underside of the box has a slight dent/hole in it.
Everything seemed to be in good working order when tested.
