"gutting" black boxes was Re: Whither goest DOS?

Denny,

In the code that runs the SBC. Many on this list could duplicate the
HARDWARE of the DeskNC or Flashcut box, but the software is
proprietary and copyright, unless declared otherwise. It is no longer
necessary to ASSERT copyright, it is implied.

Hope this helps.

P.S. As Chris S posted, a team "could" work to duplicate the
FUNCTIONALITY of the software using the same "blind" process Phoenix
used to break the IBM bios monopoly. This needs to be a strictly
controlled process to be legal.

And in our small market, I don't think we'd really be doing ourselves
any favors (thinking beyond the individual) by "breaking" flashcut,
DeskNC, or another...
