RM6 - ONYX iR
RM7 - ONYX2 iR
RM8 - ONYX2 Reality

You have ONYX2 iR so your choice is RM7 with 16 or 64 Mb texture memory.

The Display Generator on Infinite Reality can scan convert and
encode 1280x1024 to pal y/c or composite video.
1 RM7 can comfortably do 1280x1024 with 4 or 8 sample anti-aliasing.
This can be scan converted in the display generator so the quality of
anti-aliasing will be much greater. You may also want to use an external
scan convertor/encoder.

If you just want PAL RGB straight from the framebuffer then 1 RM7 on iR
can also do this.

Cheers,Angus.
