The company that made prolock is out of business - I don't know if
anybody bought up the product line.

Prolock was a particularly tricky copy protection scheme.  Prolock'd
disks have a unique laser burn fingerprint.  I've had lots of
trouble getting some prolock-protected disks to work on some
machines, and I'm not enamored with the idea of having my disk
drive heads run over an intentionally-damaged part of the diskette.

Prolock can be circumvented by a special version of the
Central Point Systems Option Board.
