The CG12 - a.k.a. the GS - is a moldy oldie now. It's a 3-slot (!!!) SBus
card, so no one in their right mind would want one. Not to mention the
fact that it's slower than a tortoise. I used to run one all the time
(SS2/GS) when I was at Sun just so I could see all the software that broke
if you used a 24-bit default visual.
The CG14 - a.k.a. the SX - is of course much more recent/interesting. But it
has some kind of funky interaction with the memory architecture, so without
docs there probably isn't a prayer at doing a proper driver for it. And lord
knows, since the GX Sun has been tighter than a sphincter when it comes to
giving up graphics device docs ...
On the potential bright side (for us), the CG14 seems to be willing to
emulate (to some degree) a CG3 in a pinch); I accidentally fired up my
built-from-scratch Solaris R6 server on an SX system one day, and damned
if the thing didn't come up ... (of course, no acceleration, etc. but hey)
