Rare Roland System 100m 172 Phaser / Chorus

via this auction
"The phase shifter and audio delay can be used for producing spatial effects. Both include convenient effect ON/OFF switches.
Both can be controlled from an external control voltage source so that two units may be used together for stereo effects, or may be used as a part of the sound synthesis process itself. The built-in control LFO has both normal and inverted outputs. The gate delay can be used where it is desirable to provide a delayed output from a pulse source, or it can be used as a pulse shaper. The gate delay also has a built-in high gain amplifier with a THRESHOLD control so that low level pulses recorded on tape can be amplified and shaped into a form which will trigger synthesizer functions."
