Lisa: Copy-protected Tools

Article ID:





    Master tool diskettes are copy protected.  The method still seems to
    confuse people to a fair degree.  This article should cover any question
    you may have about Lisa's protection scheme.

    The first time you duplicate a tool master diskette, that diskette AND its
    copy are tied to the specific Lisa you're using to perform the duplication:
    both diskettes are imprinted with that Lisa's serial number.  This
    imprinting occurs almost immediately, so even if you abort the copy, both
    diskettes will probably already be tied to that Lisa. You may make as
    many copies of that master diskette as you like, but those copies will
    run only on the Lisa that made the first copy.  Users can make as many
    back-ups as they feel necessary, while we are able to protect ourselves
    from unauthorized dissemination of Lisa software.

    The original tool master diskette may be used on any Lisa, but you will
    not be able to copy the tool onto the ProFile.

    The serial number that the diskettes are imprinted with is the one burned
    into the PROM located at position C6 on the CPU board.  If the CPU board is

    replaced for any reason, it's very important that this PROM is transferred
    to the new board; otherwise, that Lisa's user will no longer be able to use
    applications stored on his or her hard disk. If that particular PROM
    itself is bad, request a new one from your Technical Support Center.

    Files that are protected by this scheme will have the file attribute P when
    listed by the Workshop.  This attribute cannot be changed.

    Protected Lisa software distributed by Apple includes:

     - All Lisa tools, except for LisaWrite and LisaProject 3.1. (Stationary
       pads, Office System diskettes and LisaGuide are not protected.)

     - Pascal 1.0 and 2.0: PASCAL.OBJ, CODE.OBJ and EDITOR.OBJ are protected.
       (Pascal 3.0 is not protected.)

     - COBOL 1.0, 2.0, and 3.0: overlay files are protected, as well as

     - BASIC-PLUS 1.0, 2.0, and 3.0: BASIC.OBJ and EDITOR.OBJ are protected.
