  Some of the fine details might be off a little, especially with respect
  to older systems. CPU type is important in determining which graphics
  options are supported.

  Fields are

     #Z planes, implementing hardware])

  Notes:

  See http://www.sgi.com/Archive/comp.sys.sgi/audio/1994/Aug/0082.html
  for more details on audio on VME machines.

  It is not certain that VGR2 graphics is {IP6,IP12} "B" series.

  The 4D50 thru 4D85 have an audio channel, but there is no
  documentation on it and there is no SGI or third party support for it.
  SGI does not seem to have discussed it at all in the newsgroups.

  XSM graphics seems to be quite rare. Elan without a Z buffer? The
  newsgroups have mentioned it only once, but I have one so I'm sure it
  exists.

  The high-end graphics list is probably incomplete.

  Slashes usually indicate points I'm not entirely clear on. For example
  I'm unclear on whether Skywriter graphics is different than VGTX.
