Wow - that are the best pictures I've ever seen on this awesome piece of SUN vintage hardware!
I have a SPARCstation 2 by myself but never found these "graphics add-on".

On the Oracle website some infos from old docs.sun.com are still available:
* 800-5258-11 GT Graphics Subsystem Installation Manual
http://download.oracle.com/docs/cd/E19957-01/800-5258-11/preface.html
* 800-5264-11 Service Manual GT Graphics Subsystem
http://download.oracle.com/docs/cd/E19957-01/800-5264-11/preface.html

There are some information on Sun's GT (codename "Hawk") graphics subsystem by one of their developers:

I've actually emailed Mr Deering before about the Leo/ZX framebuffer he didn't have much info on it though. no manuals or anything quite disappointing. he seemed like a nice enough fellow though.

I came across a sbus host adapter for the Sun GT framebuffer. I don't have the tower. Anybody interested in the sbus card?

I do have a Leo/ZX, I used it for several years, but the performances were not there. I remember that the ZX gets REALLY hot.

"hot" is quite an understatement. Sun even sold a special fan assembly to use with the ZX in multiprocessor SS20 to prevent them from melting...

If you google around there used to be some descriptions and pics of various ss20 + ZX out there with crazy setups to keep them going. Certainly the extreme end of the heat range for the form factor. [But damn I love those old pizza boxes.]

I remember one issue I had with the ZX (but not the GC/TGC) was its lack of support of linux, which was problematic back then, as I was moving away from SunOS then on Sun4m. I still ran Solaris on Sun4u for mentor graphics for the few years afterwards.

For what it is worth there is a xf86-video-sunleo driver nowadays on linux but I have no idea if it works. I I may get around too in in the next new months since I now have a large disk in my SS5.
