During Google Summer of Code 2011, Bryce Lanham added the possibility to
emulate the NeXTcube machine in QEMU, e.g. see this URL for some details:
But since the machine requires a 68040 CPU and this was not included in
upstream QEMU in 2011 yet, the patches have never been merged to upstream.
Now in 2018, Laurent completed the full 680x0 support in upstream QEMU, so
we could finally merge the NeXTcube support, too.
The QEMU interfaces changed a lot since 2011, so I had to modify the
sources quite a bit, but with the attached patches, it is now possible
to boot up to the firmware monitor again.
Note that boot device emulation is either still missing (network), or
not working correctly yet (SCSI), so you can not boot any operating
systems with this machine yet.
Please ignore the checkpatch warnings about C99 "//" comments. There
are many of those in the sources, used to comment out alternative code
lines. I did not want to remove those yet, since some of them could
still be helpful while improving the machine emulation in the future.

Looks like the most interesting patch (patch 3) has been blocked
somewhere, presumably because it is quite large.
Is there a git repository for this patch series somewhere for the curious?
