An SGI Iris 4D-series port may be fairly straightforward (basically
there's one kind of SCSI host adaptor, the WD33C93, and one kind of
Ethernet chip, which I've forgotten, at least on the low-to-mid range
systems) except for frame buffer support: if you had an SGI workstation
I guess you would want to use the frame buffer (8-) but there are
zillions of different ones (GT, GTX, VTX, XL, XS, XZ, Elan, Extreme...)
on the various models and I doubt any of them are publically documented
at a sufficiently low level.
