Hi,

I have a color monitor that has a 9 pin connector and I would like to use
it for my i486-DX2/66 that comes with a Trident 8900C card which is a 15
pin connector.  Does any one have any idea that I can use this monitor to
my i486-DX2/66?

Thanks.

Sorry I don't have better news for you.

But be warned - If the monitor is not a VGA - You will destroy the monitor, and
probably the video card.  You will see smoke, and that's a bad thing... :)
(CGA and EGA monitors used TTL digital signals, VGA used analog signals -
completely incompatible.)

|Your monitor with 9-pin connector is either a CGA or EGA monitor. All
|VGA and SVGA monitors have the 15-pin connector because they are
|electrically incompatible with monitors having a 9-pin connectors. If
|your monitor has a composite video connector, you can use it with your
|VCR, but otherwise, it is an oversize paperweight.

Not true. I have a NEC VGA monitor with a 9 pin connector and it works
fine with my SVGA card with a 9-15 converter (but only at 640x480 of
course).  But the answer is partly right; check that it isn't a EGA or
CGA monitor first. They are not compatible with VGA electrically.  (But
I also have a mono switchable VGA/EGA monitor.)

: Well, actually, there is more than one exception, and most likely
: several.  As recent as last year, and probably up to the present day,
: Unisys  has bee selling monitors that have a 9 pin connector on the
: monitor, with a db9-db15 cable.

i have an older NEC Multisync that has a 9-pin connector.  the 9 to 15
pin adapter works fine.  and i don't really believe the claims of possible
damage, btw.  if it doesn't seem to work, just don't leave it connected.

I have an original NEC Multisync (when that was a single model)
which I bought 10 years ago this month. It has a 9 pin connector, a
switch for digital or analog, and runs well at 640x480 and 800x600,
and doesn't break at 1024x768, but it's obviously not happy at that
res.

  What do you mean I shouldn't do thing like that at my age?
  At my age if you don't do things like that you might die of natural causes!

I used to service some NEC multisync displays which *did* have a 9-pin
connector (DB-9).  These units were VGA or SVGA compatible, depending on
the model.  I think some Princetons were like this.  Contact the OEM for
specs/adapter availability.  I think I still have an old multisync 9-15 pin
adapter laying around.
