Just found a cool wee article. I think if I search for Moog 960 stuff I'm more likely to find some vintage magazines or books, but Amazon doesn't seem to be the place for rare old books.
Just found this cool we article http://www.studio250.fr/docs/divers%20synthese/sequencer.pdf.
Unfortunatley it would only work for sequencers with FM clock input. However this stuff is definetly up my street, love it, nitty gritty and intriguing.
Funny how most modern sequencers as far as I'm aware can not change individual note values and by that I don't mean gate length or note on/off. I mean, i.e. 3 notes are played as quarter notes then the following two as half notes etc.
