        Think divide and conquer.  You've got to do two main tasks.  One
is to read the clock which you have not described so it is next to
impossible to tell exactly what needs to be done, there, but you must read
the clock and be able to use the digits you got as pointers to various
addresses in the memory of the sound chip.  I haven't yet built anything
like this so I can't be any more specific, but that is the thought process
that one needs to at least start solving the problem.  If I were doing this
project, I would concern myself with controlling the voice chip first.
Look at the number of pins you will need and the protocol to address the
chip and then go from there.  The PIC, itself, can be your clock and
voice chip controller since it doesn't take but a few counters to behave
like a digital clock.  I would want to use an interrupt to serve as master
tick generator for this clock and then use the counter values to access the
words you have programmed in to the voice chip.  The tasks you must do and
the number of pins you need for doing them will dictate which PIC and which
strategy works best for your particular situation.  That is what this game
is all about and why it is fun.  If you break the task in to several smaller
ones and concentrate on just that part, you stand a good chance of ending
up with what you wanted.  As you run in to trouble with each of the small
tasks, there are probably scores on this list who have already been there
and done that but you need to supply most of the gray matter power to
bring all these small building blocks together at the end.  For some of us,
that's the only way we get anything done.
