MOTM

Bernie's "plan" was actually based on a design of mine that only extended
the conventional OTA VCO to include the through-zero modulation.  Bernie may
have had problems with it but I sure didn't!  His writeups were based on an
article of mine that Electronotes publish based on a research project that I
did.

However, it was never the precision VCO that the 300 has become.  But it
could be improved substantially and still use a more conventional "discrete"
architecture much like the 300 has (though different).  It probably would be
less complex in circuitry then the 300 but with a slight reduction of
absolute tracking accuracy.  Still I believe it would be superior to all but
something like the 300.
