I have a SID turning on and then the calc sends a song.  The SID makes a
high pitch scream and then quits...

The problem is that if we want to use the SID we have to also use a 6515
(what ever) since the SID requires atleast a 1MHz clock comming from the
host computer.  Otherwise, my beta worked.  Once I have the code for the
6515 programmed I'll post the hex...
