[sdiy] Steiner duophonic electronics and buss keybeds revisited, yes again...

[David Ingebretsen]

Good news is I have the Steiner Duophonic keyboard electronics working, and
I have a simulated buss keyboard working using Doepfer MTC64, 61 reed
switches and a resistor chain.

Still, I would love to find a 5 octave buss keybed. I appreciate I'll
probably have to locate an old organ or synth to cannibalize. 

The question then is this; is there some resource, list, book, obscure web
page, which lists which older devices used a Pratt-Read keybed or similar? 

Many thanks.

David
