Can the digital/analog barrier be broken? (Magnavox digital to IIGS analog)

[jora <jatienza@ucla.edu>]

Close to giving up the ghost, I had to temporarily retire my trusty
AppleColor RGB Monitor.  A couple of years ago, I found a Magnavox
RGB Display 80 (Model CM8764) cheap.  Unfortunately, it accepts a
TTL (digital RGBI) signal, so it was unusable on the GS, which
generates an analog signal and displays far more colors.

Now I'm just desparate for a clear monitor to do word processing
and page layout on.  Correct colors are not as important.  Having
read stories on csa2 about how people connect digital monitors to
analog RGB output and vice versa and how if the scan frequencies
are the same it should work, even though the colors are off, I'd
like to give it a shot.

The Magnavox monitor has a round DIN8 socket:

                        2
                       4 5
                      1 8 3
                       6 7

Pin
1       not connected
2       Red
3       Green
4       Blue
5       Intensity
6       Ground
7       Horizontal Sync/Composite Sync
8       Vertical Sync



The signal (from the AppleColor RGB Monitor manual) for the
GS RGB port appears to be:

Pin
1       Red video ground
2       Red composite video
3       Composite sync
4       not used
5       Green composite video
6       Green video ground
7       not used
8       not used
9       Blue composite video
10      not used
11      not used
12      not used
13      Blue video ground
14      not used
15      not used
Shell   Shell ground


So how would I make a cable connecting the two?  Would it work at
all?  Where do I connect the intensity signal, since the analog
output does not seem to have one?  What about ground from each
color?  Do they go into the common ground of the Maganavox connector.
Please post replies here.  Much thanks for any help in advance.
