To get inside the E-MU Vintage Keys synthesizer, you must lift off its top panel.

There are screws on the bottom of the synth that hold down the panel.

Flip over the synth to remove 3 screws from the right end panel and 6 screws from the left end panel.

This is the right end panel.  The three screws are in recessed holes.

The screws of the left end panel are also in recessed holes.

Finally, remove 5 screws from the rear panel.  Four of the screws are shown here.

You can remove these screws either before or after you flip the unit right-side up again.

Now you can lift up the top panel and set it behind the bottom shell.

Be careful not to pull any of the cables farther than their reach.
