[AH] Scope Snapshots of raw vintage analog waveforms

Roman is perfectly right, of course.
I just forgot about the Minimoog.
And please see also the contribution of Osamu Hoshuyama
about the waveforms not being raw VCO traces.
Which makes http://www.asahi-net.or.jp/~WZ4K-TNK/etc/wave.html
not just a great site, but a flawless one, too.
Sorry for the confusion.
