Photo of an OMS-7EII. The OMS-5EII has only 2 small buttons on the right side. On the left side of the OMS-5EII the headphone output and the volume knob are missing. The inner workings of the two devices are absolutely identical, except for the extra boards needed for the extra functions of the OMS-7EII. So I could only upgrade my OMS-5EII to remote controllability and programmability with the infrared receiver of a defective OMS-7EII.
