I have had the DiamondScan for about 20 months and have been using it for
Alpha and Beta testing new Amiga OS.  There are still some special problems
in using productivity mode with the DiamondScan; however, using the CSYNC
line will not allow any productivity mode use at all ( the 31.5 kHz scan
rate ).

On the other hand, the A2300 genlock does not pass HSYNC and VSYNC, so the 
above described cable is the only one that would work.  For my own use, I
buy the 23 pin cable without a termination.  That way I can wire them to
the connector I need. ( I also use some Sony monitors ).  I have several
cables made up depending on use ( including the exotic genlock inside the 
monitor modes inside the DiamondScan and the Sony monitors ).
