Personally I'd like to see the obsolete Sun Hardware

Then you need to ask for it, specifying exactly which pieces of
you're interested in - see the current status of requests and doc
I have checked that URL; it seems that nobody has asked for release of
docs/drivers for the cgfourteen (aka SX) graphics found in SS10s and
cg14 and SX aren't the same thing.
SX is a rendering engine soldered to the mainboard, cg14 is a VRAM
module with a fancy DAC bolted to its side. The SX can render into a
cg14 or main memory, it doesn't distinguish between them at all.
We know how to handle a cg14 - it's just a semi-dumb framebuffer
after all, but we do not have the tiniest shred of information about
the SX which is why we don't support any acceleration on it.
It also seems that Sun will actually start looking for requested
and has in some cases succeeded in supplying the desired information.
I sent a request for docs, among others for the SX - the only
response I got was a message stating that my request has been received.
