This is better known as a Voyetra Eight, but its original name was Voyager Eight when it first appeared in July 1981.
Octave-Plateau also made a monophonic Voyager One rackmount at the same time, but I’ve never seen one anywhere.
These are NOT photoshopped - I scanned these out of my keyboard magazine archives.
edit: The forum crops these pics, the large format pics are here
