serial or graphics adapter for VAXstation 4000/60

Hi,

I hope someone of the VAX users can help me here. I got a VAXstation 4000/60 
some weeks ago. Up to now I am more or less unable to use the box, as I seem 
to be unable to find a serial RS423 to DB25 or DB9 adapter, or an adapter 
for the graphics card to an ordinary PC graphics connector. Also not on 
e-bay. 

Anybody has an idea where I get an serial or maybe a graphics adapter?
I have no fitting plug for the RS423 connector, so I already opened the box, 
and it seems I could solder a DB9 or DB25 to the outlet directly onto the 
board. Does anybody has an idea which pins I have to connect to make the 
adapter work as a null modem?

kind regards
Sebastian
