[sdiy] 40106 astable multivibrator - origins

[S Ridley]

I think RCA were the first to manufacture CMOS, so early RCA databooks
would be a good place to look.

The 1973 databook:

http://www.introni.it/pdf/RCA%20-%20CMOS%20Ic%20Databook%20SSD%20250C%201973.pdf

has a 40106 datasheet and an astable circuit.  The 40106 was near the end
of the list in this book, so I don't think you'd have to look very much
further back.  1972 perhaps?


I wonder which synth was first to use CMOS?
