Click here for a sordid tale of the Gibson Oberheim OB-Mx. If you haven't read this before, make the time to do so. It's an interesting bit of synth history.

"D.N. "Lynx" Crowe and Don Buchla were called in to salvage the OB-Mx very late in the game. They weren't told the whole story of the project to that date; they gradually uncovered the archeological and forensic evidence in the drawings and code. Some details still aren't known, but thanks to the process of Discovery in several civil suits, including depositions of many of the people mentioned here, enough is known to show the mismanagement, fraud, and incompetence that doomed G-WIZ, the OB-Mx, and ultimately OpCode and any other hi-tech company that is fooled into trying to work with Gibson Guitar and its Technohick CEO, Henry Juszkiewicz. Everything spelled out in this narrative is either from my own memories of the time, or from depositions and exhibits already in evidence in the case."
