SGIs are MIPS machines (except perhaps the earliest ones, but the 4Ds
are MIPS).  There were ports to one of the SGI Challenge machines and
I believe the Indy or Indigo.  I can't recall if these were ever
distributed, and kittens are destroying my office, so I'm not going to
spend the time to find out.  Anyway, 4e doesn't include any SGI ports
and SGI never made it easy to get the sort of information (e.g.,
physical memory map, MMU details) that you'd need to port to their
machines, and I think there was quite a bit of variation, though
probably not as much as across Sun's product line, where it seemed
that every new model had a new incompatible MMU.  For terminals, the
frame buffers seemed to all be different and incompatible.
