Is this the coolest musical toy ever made? eBay #7341987803 is a Muson Synthesizer from 1978. MiniOrgan.com says: "Incredible Machine. Far ahead of its time - a mini sequencer with endless possibilites. Kind of a ROLAND TB-303 but much cooler & cheaper. The coloured buttons can be used to change the melody and rhythm - each color has a different tune. You can also change the speed and pitch of the sequence with 2 sliders. My neighbours thought this was my new car-alarm." Currently 99p, with almost a week to go.
