  How old is your source?  There was a small bug in printing out the
physical address of the bounce buffer.  It was using the macro to
compute the physical address of a Zorro II I/O address, which is not
correct for a Zorro II memory address.  That should have been fixed
in the current source (October 6 is the last change date in my copy
of gtsc.c).
