According to Nick J. Biggs, host of a nice website concerning the Novag
Universal Chessboard (http://www.pawn.demon.co.uk/UCBProt.htm), the UCB has two
identical 6-pin RJ11 sockets, one just for connecting to the Sapphire or Diamond
(which also have RJ11 sockets) and one for connecting to the PC, with a switch
to activate one vs. the other.  This leads me to a few hypotheses: the two lines
may have different voltages and pinouts (RS-232 vs. RS-422 for example), and the
data rate and protocol is likely to be the same for both ports.

This leads me to ask about the Distributor.  Does anyone actually own one?  It
would surprise me, since I can't find anyone who is actively marketing it.  Not
even the Novag web site gives it a mention (though their ads say that the
Sapphire and Diamond "Easily connect to any PC via serial port", as if the
capability were built in!)  I've been told that some of the Sapphire's
advertised features (user programmable book, game analysis, rate-your-play) only
work in conjunction with the Distributor.  Sounds like bait-and-switch to me.

What comes with this $70 Distributor?  Does it require a power supply?  Does it
require or come bundled with software on the PC?  Is it compatible with a UNIX
or Macintosh computer?  Does it have any other bells and whistles?  Or is it
just an overpriced serial cable?

Any information would be appreciated.
