Ah yes, it's an old trick. My sketch has a clock output (pin 8 I think).  Pin 9.

Successfully flashed the fuses--now it's using the internal oscillator! Thank you for your help. Now to what I actually want to do... set up a watch crystal asynchronously! Time to hit the datasheet.

I seem to recall someone doing that, not so long back. a 32.768 KHz crystal or some such thing. Or maybe that was as an input to a timer. One or the other.
