Help wanted for RS/6000 video output

[Li Ming]

Hi,netter,I am using a finite element analysis program (ANSYS) 
in RS/6000. I want to record actual graphics as they appear on
the screen,such as real-time 3-D rotation. But the color display
of RS/6000 (IBM 6091-19) only gives RGB signal output, not the
NTSC video signal. I think there exists an encoder to combine 
and transfer the RGB signals into the NTSC video signal but I
don't know how to get it. Can someone in the net help me get 
the information about it? Thanks in advance.
