"These units are rare as only roughly 600 were made over a decade ago. Here is some more info about the unit:

'The 777 is a monophonic analog synthesizer with a digital sequencer. Built with the highest quality of components, the 777 is housed in a rugged aluminum chassis, has solid cherry end pieces, with top of the line knobs, switches, and electrical components. This machine is built to last.

The 777 is capable of reproducing the oh-so-famous sound of the TB-303 in every way, but that's the least of it. TheTB-303 has only six knobs and one switch to control the sound, while the 777 has all these, plus five times more. There are 32 knobs and 7 switches to be exact, all instantly available with their single dedicated feature. The sequencer part of the synthesizer contains 28 illuminated keys, keeping all the features readily available for the user to tweak at any time. No menus, no virtual analog synthesis--this is the real thing!

Not only can the 777 recreate the TB-303 sounds to a "T" (or should we say "TB"), but it can also produce everything from deep basses to lead synthesizer parts, electronic percussion (kick drums, high hats, snares, toms, etc.), plus all the crazy ambient sounds you can dream of. This is the instrument of the future!

It's fat, it's warm, it's fuzzy, and it's packed with oodles of cool features. Let's start with the seven possible audio sources. There's Oscillator A and B, which both have a continuously variable waveshape from saw tooth to square. Then there's Sub Oscillator A and B, each being one octave in pitch lower than their respective oscillator and both having square waveforms, with the exception that Sub A has a higher frequency content than Sub B. Also available are a white noise source and an external input jack that allows any external audio to be routed through the filter and amplifier section. And, the filter is capable of self-oscillation, producing sine waves.

For frequency modulation, you can modulate Osc A's frequency with Osc B and Osc B's frequency with Osc A. An envelope is also provided to sweep Osc B's frequency.

The Filter section contains a selectable 3-pole or 7-pole lowpass filter complete with cutoff, resonance, res max, and accent controls. A highpass filter is provided with an adjustable cutoff. A pre-filter gain stage is also standard to fatten up the oscillators.

On the Filter Modulation section, a selectable CV-type switch is present with normal (Standard key follow type), and warp modes. The control voltage amount is also adjustable. Then there's the continuously variable waveshape control to set the shape for Oscillator B's frequency to modulate the filter, plus its amount control. There's also a dedicated envelope with adjustable decay time and amount controls.

Finally, in the Amplifier section, there's an accent decay and normal decay control for the amplifier's envelope. You can select either the envelope or a gate to control the Amplifier section. There's a bass control switch to select either normal or boost. Two different types of overdrives are available with an amount control. There's also an amplifier accent control, and last but not least a volume knob.

You're probably saying to yourself, "Hey this thing doesn't have any LFOs or built-in effects." Actually, you can get everything from tremolo effects to chorusing and phasing to massive distortion. It all depends on the sound parameters. Users will find that the oscillator cross-modulation can produce an extreme amount of new sounds and effects. Remember, this keyboard doesn't fit well in the norm of features given on most synthesizers--it goes beyond those limits to complete new possibilities.

The sequencer in the 777 is one of the easiest you will ever use, yet it's still packed with unique features. There are 256 recordable patterns available, each recording note duration, pitch, accent , glide, loop point, and time signature. If that's not enough, all editing and recording can be done while the sequencer is running, and it will automatically save all your edits so you don't have to stop creating! There are 16 songs to arrange the patterns in, each recording its tempo, the bank/pattern for each step, the transposition of each step, and the song loop point. Each of the 16 songs can contain up to 3,580 measures, which is a lot!
The 777 also comes with MIDI for those who like to communicate with machines. You can synchronize via MIDI to an external clock or have the 777 act as a master device, sending clock signals to external sequencers, plus send and receive MIDI Note data, and velocity. The 777 also supports SysEx dumping of patterns and songs. And we wouldn't want to leave out our brothers, the firm believers in analog, so we included control voltage in/out, gate in/out, accent in/out, filter in, and audio out 1/4" jacks on the back panel. You can also use the 777 as a MIDI to control voltage converter with CV, Gate, and Accent outputs being controlled by MIDI.'"
