I have a Mono CGA monitor (Samsung). It has a DB9 connector only with
the pins:
- Ground
- Intensity (I)
- VSync
- HSync
- Reserved (?)

I did a DB15 to DB9 cable (I have the Laser DB15 pin documentation)
with this signals. But it doesn't work !!!! I read that the CGA isn't
an analog RGB, so, it doesn't work. Do you know how can I do this work
?

Thanks,
