DB15 to DB25

[Doc Thirst]

I'm trying to locate an adapter to go from my video out (15 pin) on my computer to a 'computer in' (25 pin) on an old Sony PVM2530.  I'm not sure if this is even possible, but I figure I should ask the experts.  I did some google and msn searches but didn't find anything.  I also search these forums for any reference to 25 pin connectors but all I found was control panel talk.  Suggestions?

9.12) Pinouts for Sony PVM-2030 and PVM-2530 Profeel Pro monitors

(From: Rob Myers (myer3812@nova.gmi.edu)).

I have the pinouts for the RGB connectors on newer Sony monitors
(specifically, the PVM-2030 and PVM-2530 Profeel Pro monitors).  These pinouts
are directly from the owner's manual.  The connector used is a DB25 female. 

High state = 5V (open)
Low state  = 0V (short to ground)

Note On Pins 3,4,5,6,11:

If pin 9 is high/open (Analog RGB mode) then .7Vpp, 75 ohm signals must
be input to these pins.  Pins 1 and 25 are not used.

If pin 9 is low (Digital RGB mode) then TTL signals must be input to
these pins.  Pins 1 and 25 are only used in this mode.

Pin   Signal         Descr
---------------------------------------------------------------
1     IBM Select     High: IBM mode (RGBI)
                     Low:  3 Bit TTL (RGB)

2     Audio Select   High: Audio input from pin 13
                     Low:  Audio input from LINE A/B/VTR jacks

3     HSync/CSync    Horizontal or Composite Sync, Negative Pol.

4     Blue Input     Video Inputs: Positive Pol.

5     Green Input    (Sync on green optional in analog mode)

6     Red Input

7     NC

8     NC

9     Analog/Digital High: Analog mode
                     Low:  Digital mode

10    RGB/Normal     High: RGB input selected
                     Low:  LINE A/B/VTR input selected

11    VSync          Vertical Sync, Negative Pol.

12    Blanking       High: Video input from RGB input only
                     Low:  LINE A/B/VTR signal is superimposed over
                           signal from RGB input

13    Audio Input    -5 dB / 100% mod.

14    NC

15-24 Ground

25    intensity      Positive Pol.

These monitors are regular NTSC monitors, but I'm sure they can be
connected to computers the same way I connected the KX-2501... using a
simple buffer circuit and special video drivers.  Another possibility is
to build a component-to-RGB converter for really high quality DVD
playback (better than S-Video)... the blanking feature seems interesting
but the RGB source would have to be synchronized with the composite
source.  I think the KX's/XBR's have the blanking input, too.

The Sony RGB Multi Input pinout is also valid for the KV-25XBR; it should also
work with the KV-20XBR and KX-1901, and I know it works with a KX-2501.  (The
KX series monitors are the original Sony Profeel monitors from about 1983, and
they are very common.)

A female 34-pin floppy connector will mate with the Sony connector just fine.
I was able to use the analog RGB input on a KX-2501 to display VGA PC video
using a sync level converter circuit and drivers from:

Wow!  That was more then I could have hoped for.  Thanks a ton for the information.  I'll see what I can do.
