Clef Master Rhythm Computer Band-box Vintage Drum Machine Synth

Pics of the inside below.

"This Clef Master Rhythm Computer Band Box is a rare vintage analogue drum machine with auto accompaniment. It is partly working and comes with its original instructions.

I have tested the machine using headphones: The drum machine section works as it should although the control knob seems to be set so that it points 90 degrees form where it should, which fooled me for a while! The chord and bass accompaniment section is not working. It does show some signs of life in that the digital display sometimes lights up when you turn it on and always flashes on for a brief while when you press the reset button, as shown in the photos. The instructions state at one point that the display should show '01 CLEF En' when you turn it on or reset it and 'En Line No' during some of the backing playback."
