This x0xb0x is fully functional and in good condition. It does not include a power supply (9V AC 500mA).
The x0xb0x is analog bass synthesizer/sequencer closely modeled after the Roland TB-303. It has many functional improvements including, easier programming interface, MIDI & DIN sync compatibility, and expanded pattern memory. The CV and Gate outputs make the x0xb0x an ideal sequencer for vintage analog an modular synths.
