Ooh, gee, I don't know if I'd consider selling it at this point. I've done too much to it and it's not really in saleable condition.
Take a look at it here:
http://www.glitched.org/stuff (it's in the second section. By the way, that page also outlines a mod that I'm quite happy to have found: a high-rate LFO.)
My 202 has the following mods:
+New CV/Gate inputs (if you try to use an external CV/Gate interface on the original inputs, you will be disappointed. There's latency that prevents one from using the 202 like a 101.)
+Audio VCF IN
+VCF CV IN
+Mod CV IN (I think I did this one wrong, but what it does is pretty interesting)
+Pulse VCO OUT
+SUB VCO OUT
+"Hidden" Triangle VCO to mixer
+Audio-rate LFO (great for cross/ring mod sounds)
My page also has a couple audio samples. Oh and yes, I did all of these mods myself. They weren't that difficult once I found some links about them on the net. (That high-rate LFO one I figured out, though.)
If there's more, just email or PM.
