Interesting. Thanks for that, Kevin. 
I looked it up- M083 and TDA1008s.
The TDAs are both dividers and keyboard interface chips (keyers.)
They reduce the parts count and current consumption and are common to find in organs and string synths (like Arps.)
Only you could look something up and find that it’s the same info from the top of your head. 
Very cool!
I like the Zep vid better than my memory, I had completely forgotton about that song.
It was one of my favs in jr high.
Nice job on that intro, I can imagine the ascending minor scale starting.
Opus3 isn’t usually brought up alongside other polyphonic Moogs because, well it isn’t quite a polyphonic synth in the traditional sense. It has three sections: brass, organ, and strings. Apart from a low pass filter on the brass section, a set of drawbars on the organ section, and a chorus on the string section, there aren’t a whole lot of parameters available for tweaking. It’s a great sounding synth, but it generally doesn’t have that very classic and expected polysynth sound. That is to say it does what it does very well, but it doesn’t do what most other polysynths do.
The Moog Opus 3 is, in reality, paraphonic. Meaning that it offers only one global filter and one global VCA.
BTW, the Moog Polymoog that came before it was also paraphonic. And parts of its circuits designs were later re-used in the Opus 3 , and MG-1.
The only truly polyphonic Moog in every sense of the term was and still is to this day, over 30 years later, the Memorymoog.

What is your point exactly ? I didn’t say “the only analog polyphonic synth”. I said “the only Moog truly polyphonic synth”…
sorry , i read" the only true analog polysynth"
so i gave my opinion about, what i would like to see under the mini.
i also thought of the opus ( very nice synth/string ), and even the jd800 and neuron for their pad capacities
I thought so…
This is a list of analog polysynths that would, in my very humble opinion, fit very well under my Mini :
Memorymoog
Prophet 5
OBXa
Jupiter 8
CS80
Andromeda A6
No GX-1? That would be MY first choice, but maybe you’re looking at affordability?
I was looking for: 1- availability, and 2- portability… If you can call a 200 pounds CS80 portable…
But the GX-1 at 2000+ pounds 
would be too much even for my bedroom floor…
That makes sense. 
Info on the net shows the GX-1 alone is about 680 pounds, the pedals add another 80. Each of the Tone ( Speaker) cabinets are about 310 pounds each… A few of the users ( Keith Emerson for one ) did not use Yamaha’s speakers with it or the pedals. The GX-1 can make some great sounds. Very few made, reports have it anywhere from 10 to a few hundred. Oh, you say you want the bench…add 160 pounds.
To come back on topic, just came up from the studio playing my Model D, Voyager, LP and other fun toys. Maybe I’ll record next time .
