I didn't realize the CG3 was programmable in any way. Is it only in the
or are the standalone, fixed-resolution CG3 also (somewhat) programmable?

especially meaning of the flag/control bits)

There was some Sun documentation for the TGX on the net once, and the
BT467 RAMDAC is documented as well...

As for SDTV - I don't understand the question; it's only 480i or 576i,
both of which are much lower than the
standard Sun 1152x900@(66Hz or 76Hz). A TGX can output 720x576 or
720x480 non-interlaced, though
I'm unsure whether the pixel clock can be set _low_ enough ...
(Interlaced is 13.5 MHz, non-interlaced is 27 Mhz).
