CA3046 replacemnt ?

[jhaible]

I used to have a TCA-something part for my first VCOs (JH-2,
pre-synth-diy and analogue-heaven development,not that proud
of it (;->) ). Same pinout as 3046 and 3086, but substrate was
*not* at pin 13. So there may be more versions of these standard arrays
than we know ...

BTW, does anybody know if the CD7007 works in applications for
this CA3600 (? - not sure about the number) device ?

JH.
