I don't have any pictures yet, but at some point soon I expect to be
buying a digital camera and will be putting lots of pictures of my
collection on the computer graphics history museum.  RISC/os was
created by MIPS and licensed to various workstation manufacturers.
E&S wasn't the only one to use RISC/os.  IRIX is influenced by RISC/os
but is not a pure derivative of it, according to 
<http://www.tliquest.net/ryan/sgi/irix_versions.html>.  I guess IRIX
was around on the 68K based SGI boxes before they mvoed to the MIPS 
architcture.

OK, makese sense now and yeah, I don't see those around :-).
