     A couple Computist articles dealt with Playroom-- one by Blackbird

and one by Jack Moravetz. Both say that that you can deprotect the

program by first making a copy of Disk 1 using any whole-disk copier

that will ignore errors. BB suggests Locksmith 6.0's Fast-copy. (Or,

formatting a ProDOS diskette and copying the individual files from Disk

1 to the new diskette may work.)



     The copy, of course, will not work. You need to change a few bytes

on your new copy. Copy II+'s sector editor works fine for this.



     If your copy is similar to the one mentioned you should find the

stuff to change on Track 05, Sector 0A. If bytes $1F-$21 are 4C 47 64,

cursor down to the first byte (using the I, J, K, M keys).  When you're

on the 4C, press H to get into Hex entry mode and type 18 [Return] 60

[Return] EA [Return]. Press ESC and Write the changed sector to the

diskette.



     The other diskettes should not be protected and can be copied with

any copier.



     Once you're sure the new copy works, you can make as many backups

as you need using any quick diskette copier.
