E-mu Emax II keyboard

The Emax II is a stereo 16-bit sampler, designed to faithfully reproduce sound across 10 octaves with 16-voice polyphony. It features SCSI, 8 assignable outputs, and 1 Meg of RAM, expandable to 8 Meg.

The Emax II used two different styles of keys; K39W keys are essentially flat on the bottom, while K41W keys look the same, except for an extra 'foot' protruding downward near the back of the key.
