It would be interesting to know what the clock limits would be on the board layout itself assuming some world where you’d want to shove an FPGA/ASIC/modern RAM/etc into the existing sockets. I think multi-core with MMU would be really interesting since then you could use GEOS for some modern workloads. I suspect at least a hyderthreading version of this would be possible on something like the C64 Ultimate since it would mostly need to track a handful of extra registers if you did not care about hardware memory protection.
