Don't know about CPYAT2PC, but I have had success with the following method:

KEY--->	1) Format the disk on the 360K drive
	2) Copy the files you want to it using the 1.2MByte drive.

It seems that the formatting is what kills the portability..once formatted,
the thing seems to work so a 360K drive can read the disk.  Of course, if you
don't have access to a 360K drive to do the original format, you're stuck.
