Subject:          Re: Moog system 55 vs IIIc


     Old Moog modulars include Model 10, Ic, IIc, IIIc, Ip, IIp, and IIIp.
     
     The "c" means console (piece of furniture) with angled front panel. 
     The "p" means portable, in tolex-covered cases. The cover of 
     "Switched-on Bach" shows a Model IIIp.
     
     Not-so-old Moog modulars include Model 15, Model 35, and Model 55.
     
     The "roman-numeral" models used the older series VCO's: 901A 
     Oscillator Driver and 901B Oscillator pairs, or the 901 VCO which was 
     pretty much both combined.
     
     The "multiple-of-five" models used the newer 921-series VCO's: 921A 
     Oscillator Driver and 921B Oscillator, or the 921 VCO.
     
     These models were off-the-shelf configurations. Many Moogs out there 
     are custom configurations.
     
     Just about all live shows with Moog modulars used the "p" cabinets 
     (Tangerine Dream, Klaus Shulze, etc.). A noteable exception to this 
     was Keith Emerson's custom modular in "c" cabinets - five stacked to 
     be exact.
     
     As for module lists - I'll dig up my old doc's for ya.
