Good to hear that this developement is still in the pipeline! One of the things that im curious of is if the old JH3 dual vco schematic works with Rev.G, i also posess 2 A-111(-1) for doing test but i dont want to mess up an older type 3340 by poking around finding the right pin to insert a sync signal from another. Whenever i do have (safely) done some tests with results ill post it here.
