I am posting this request for a friend who does not have access to usenet news.

The Commodore 1541 disk drive has a routine to search for a sync character on
a formatted disk.  This routine ($F556) reads bit 7 (sync detect line) of $1C00
to detect the sync character.  My question is, where (and what) is the routine
that updates the ram location $1C00?  If anyone out there in netland has an
answer please send me mail that I can forward to my friend.

All help would would be greatly appreciated.
