[sdiy] [OT] LM13700 spotted in commercial product of big Manufacturer

[Paul Perry]

I would pay good money to watch a soldering race (tools and component sizes
optional).
First to a working unit wins. The original Olympics were relevant to the
society of the day, why not now?
(This can't be extended to creating software synths, because none of these
have ever reached a final bug-free state.)
