DjDelay, mate - i'm sure you'll find your answer right here: http://www.sequencer.de/moogulatorium/analog_moog.html
here's a quote from that page: "so the 70ies ,thats the big time of the minimoog and still it is one of the most warm and full "phatt" sounding synthesizer ever made - I compared it to my moog modular system and the result is: it is very close - it's only minimal more warmth in the modular, so imagine the first mini prototype as the 904 filter (a) LPF, 2 simplified ENVs and 3 OSCs with mixer. no lfo. use an osc as lfo.mini synthesizer".
