Cool. Thanks. We used to make crystal oscillators using inverter ICs (I'd
like to say they were 7400 series hex inverters but I'm not sure.) and I
suspect these would go well with one of them. But then, these were the same
days we used to use RTL914 dual 2-input NOR gates for about everything
linear. There were some DTL gates that could be linearized as well but I
can't remember which ones.

Which reminds me, if anyone has any 914s around, I'm very interested in
acquiring them. Same with National INS8073 SC/MP processors. (These were
the last type made.)
