Can Parallels Run Tiger (10.4) ?

Hello,

My father had an old G5 that recently kicked the bucket. All his data was backed up on an external hardrive with time machine, and he has all of his program disks. Some of the program's are not compatible with Leopard, let alone Snow Leopard. He is pretty upset at the moment.

If parallels can run Tiger virtually than I am going to get him a new Imac. If this is not possible I guess I will see if I can pick up a used G5.

If parallels can run Tiger virtually is the setting it up going to be pretty much the same an setting up windows 7 in parallels?

Thanks for any feedback, and or suggestions.
