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.
