Ober-Moog development chronology
from Greg Rule's Questions page in Keyboard Magazine May 1994
Malcolm Doak of Oberheim described the development process which I am condensing here.
July 1990: Gibson acquires Oberheim
July 19 1990: Product conception begins - goal is 6 month development for Winter NAMM intro
Originally planned as a quartered OB-8 with a now public domain Moog filter.
July 23 1990: Microprocessor changed from the often used Z-80 to the 80C196
Late 1990: First prototypes = SEM color/font, OB-8 controls and Moog knobs
January 1991: Winter NAMM debut - no LCD. Two weeks later LCD panel created for panel #2
Early Summer: All new internal hardware. One team member resigns, VCO problems.
January 1992: Winter NAMM = 3rd panel
1992: Other developers bail. 4th front panel. Disorganization - complicated & messy software/hardware development = product cancellation.
January 1993: New development team lead by Don Buchla and Keith McMillen redesign and create the OB-Mx as we know it.
March 1994: The OB-Mx ships
