Another thing to try, if the discs are readable by the candidate Mac,
is to get and use CharleSoft utility, Pacifist. You can read disc installer
sets and choose to see what, if any, applications or content could be
used in another computer.
This can be problematic and it is best to just have the correct discs
and be able to run an installer for the software as intended. That said,
it is sometimes possible to use Pacifist to install from a different set
of software installer discs, since it will recompile the packages on
the desktop of the computer the software would be installed on. It
takes parts off the installer disc media, so it would ask for them to
get all the parts prior to building a package the machine could use.
And if you are using software intended for another computer, it can't
be shared. If the software is in place, in use, in another Mac, the
same one can't legally be used in two at the same time. But, if the
software set has been superseded by a newer OS X and that set
is idling, of no use, then the single-user license may be seen as
not broken if you (the primary owner) decide to experiment some.
But since I am not a part of Apple, Inc nor do I represent Apple
Legal, you can take my opines as a grain of salt. Their rules apply.
In any event...
Good luck & happy computing! 🙂
