I recently purchased a Kraft 14-inch monochrome monitor for my
Amiga, but I can't seem to get it to work correctly.  The monitor
has a db-9 connector that looks like this:
            CGA                    TTL
        1 - ground               ground
        2 - ground               ground
        3 - digital red          reserved
        4 - digital green        reserved
        5 - digital blue         reserved
        6 - digital intensity    intensity
        7 - reserved             video
        8 - horiz. sync.         horiz. sync.
        9 - vertical sync.       vertical sync.

It is obviously a dual-mode monitor.  I made a cable that 
(supposedly) connects the Amiga 1000 up to a CGA-compatible
(RGBI) monitor, but no-go.  The machine boots, but the screen
never even shows hints of light.  I know the monitor works
on a monochrome PC, so that's not the problem.  And it looks
incredible since it's built for interlace, so I'd really
like to get it to work with the Amiga.

Does anybody know any reasons why it might not be working
for me?  I would really appretiate any help that anyone could
give.  Thanks alot.    -Mike
