(aka firmware) If so, consider one of the tiny micros. The PIC 12F629 comes in an 8 pin DIP. It doesn't require any external components. (Maybe a socket.) It's got an 8 bit prescaler on Timer0. That would drop 10 MHz down to something you could watch with software. You even have a couple of pins leftover for other hacks. I think there are similar chips available in SOT-3-6 if space is critical. -- These are my opinions, not necessarily my employer's.
