Flashing of the FPGA circuitry with a new CPU core is done while the system is running, and they keep increasing the execution speed of the CPU with every update. The thing is nuts.
In theory, once MMU support is added, it should be possible to port illumos back to MC68000, since SunOS 4 used to run on that CPU years back. Solaris zones, DTrace and ZFS on Amiga hardware... now that’s what I’d call a hacking project.
