Again, thanks Jim.

After I read your first message, I googled with different keywords. As
a result, I did find a schematic which showed a 4584 cmos gate
oscillator with the input (Vcc) varied to control the output
frequency. With an R of 2.2 meg and a C of 220 pf, the author claims
that 2.5v in produces 1 Khz out and 9v in produces 20.8Khz out.

That's a ST hex inverter.

I'd post it, but I think binary attachments are forbidden here.

just post a link, like this one:
