- What if a program was HALF copy-protected? What if software came with
- a facility to make itself work only on a specific machine?
-
- (A few months ago on this newsgroup I saw a lot of suggestions on how
- to do this, including checksumming the ROM.)
-
- The software can be installed easily FROM THE ORIGINAL DISKS onto
- any number of machines any number of times. The original installation
- disks may be copied by DOS. BUT, once installed, the software cannot be
- copied from the hard disk to a different machine. (At least not easily.)
-
- Here's the motivation. We accept the fact that someone who owns the
- program can install it on more machines than he/she should. We try not
- to make the owner's life difficult. But no one can copy the program
- without the owner's permission.
-
- This would be helpful at computer labs where many people use software,
- but only a few people are responsible for the computers. This would
- neither help nor hurt an individual who buys software for personal use
- at home.
