now you've got it, and you can do exactly the same thing with individual panel memories off any disk too. The registrations stand, all you have to do is change the composer they point to.

Lanny, Carol started off with 2 disks, so disk load is the easiest way providing the files are all in 7000 format. If patterns are already in composer B and C you can use composer copy, but this would be unnecessary complication if starting from 2 disks.
