Just acquired a few more pieces from Ebay: a Kawai K3m, a digital wave synth with real analog filters and envelopes (yummy), and a Casio VZ-8m, a really digital synth with nothing analog about it. Being the sadist that I am, I love reading through the manuals, but alas, ain't got none.

Then comes Mark S. Glinsky to save the day. He has manuals in pdf form for a few bucks each... Highly recommended.
