GaryB:  Check out this manual.

Bud Weiser:  Wow, that's possibly the oldest manual I've seen, much older than my printed one and less pages.  The control accessories on page 17 refer to numbers  I've never heard from.  I've found another PDF on the web and it's similar, but some pages written in July and December 1971.  Both manuals refer to the 'RA MOOG' (Trumansburg/ NY) and 'Musonics' (Williamsville/NY - move November 1971) Minimoog D. These have the old OSC-boards (less trimmers,- and less related holes in back panel) which had much more tuning drift and temperature stability problems.  This was fixed introducing the heat chips as a modification and later a new OSC board carrying these chips.  Serial #10175 is the 1st one with the new board if I remember correctly.  When it became Moog Music it was 1972 already.

#958 foot pedal became MOOG 1120 CV pedal, new ft-switch, the ribbon controller and sample&hold as well as the Moog drum controller appeared more or less all derived from the big modular systems.

Now, talking Minimax, it would be interesting to know which Minimoog D was modeled, a RA model, a Musonics or the later 'standard' Minimoog D from Moog Music.  They all sound and behave a bit different even though they look identical.  Who knows ?  Holger, Rolf Meurer ?

Keith Emerson used the ribbon controller w/ his MOOG Modular already.  Billy Cobham used the Moog drum controller w/ his Minimoog already on 'Billy Cobham - Spectrum' while Jan Hammer used the Moog S&H generator, switches and pedals with his Minimoogs on the same record.  All these little pieces between the tunes on that album are full of MOOG FX.  It's one of my all-time favourite albums, last but not least because the tasteful guitars came from Tommy Bolin.  Lots of that technology also used on 'Mahavishnu Orchestra - Birds of Fire'.

For the Moog Modular there was a module called the 'Bode Frequency Shifter' which later became a standalone unit too on Jan Hammer's request and replacing his Oberheim ring modulator being used excessively with the Fender Rhodes pianos.  I wish we had such device for SCOPE Modular including the option of controlling frequency sweep by MIDI CC #04 foot controller.  That's what he did using the 1120 CV pedal together w/ the Bode.  Listen to Jan Hammer 'The 1st Seven Days' all the bell tones were done with the Fender Rhodes and the MOOG/Bode Frequency Shifter.  Also listen to the electric piano solo on the Billy Cobham title 'Red Baron'.
