BTW, I asked Micko about this a while ago already, is there interest in emulating sun4u/sparcv9 systems in the "not too far" future? I have a few... two Ultra-1's, two Ultra-10's and two E250's.
I know the architecture is complex, but I still hope these systems will eventually be added. All I can do to support it is a bit of documentation (
sparc-docs.zip, well some PDFs are quite comprehensive), offering images and (if I knew how to do it) probably dumps.
