The Ace Tone 3000 was probably the last home organ before the label was absorbed into the new Roland label in 1972. The model, designed in Japan, was distributed by Jorgenson in Denmark. Its technology was based on the Hammond Cadette series. Hammond F-3000 (produced in England) is a variant of the Ace Tone 3000 (source: Wikipedia).
A recording tape recorder is built in at the bottom right, drum keys (Cha-Cha, Beguine, Bossa Nova, Fox Trot, Rock'n Roll, Slow Rock, March, Waltz) are available at the bottom left. The pedal section includes an octave.
