This reminds me the ultimate challenge: re-program the OS to take advantage of the CL memory space... a daunting and probably useless project considering the immense amount of work required, the likelihood of messing up a wonderful design, and the little to no use to anybody except the three usual suspects.... although these very same three considerations may also be the definition of a dream challenge ;-)

Well, maybe not the complete OS but I'd start with the extended memory management - all those voids in-between modules are a real shack and hassle and sure could go away if we put the work to it. Is this feasible?

For compatibility, those holes are enforced by the 41CL hardware. So even though the RAM is present in all those locations, the CPU fetches data from the bus rather than the RAM in those holes. Changing that would require reprogramming the FPGA.
