    This project started a few weeks ago, in fact. I took rotary dial and partially breadboarded the dialing circuit.

    No big deal, just a little bit of sequential logic and contact debouncing. The dialing circuit alone contains 14 ICs and it will grow up more. Stay tuned for more TTL ICs and detailed circuit descriptions.
