Title link takes you to a number of soft synths from Rick Jelliffe including CS-80, SH-3A, and of course, the Neumixturtrautonium mentioned in this post.
EVERYTHING SYNTH

Title link takes you to shots saved from this auction. Check out the extra knobs on top. Anyone know what that is? It almost looks photoshopped. There is no mention of the knobs in the auction. This one in via underface.
Title link takes you to Mark's thoughts on the Moogerfooger MF-104. He touches on the differences between analog and digital delays and he has very nice sample of the MF-104. If you ever wondered what an MF-104 sounded like, let alone what an analog delay sounded like, check it out. What's great about the demo is that it shows a wider range than typical demos. There is also a timeline on the page so you can read what's happening as you listen.
"This modification to the Poly-800 series of synthesizers adds the ability to control Filter Cutoff with DCO1. This is commonly known as FM control of a filter. Although it's technically not Frequency Modulation, the results are capable of sounding very much like an FM synthesizer. A knob allows the effect to be turned from completely off, to far beyond the normal capabilities of a Poly-800. This modification very nicely compliments the Moog Slayer modification for a total of 3 knobs full of fun."
