Over the years there were many variations of extended addressing for
mostly Z80 systems using MMU or bank switching. We also had Z180/64180, Z280 and other variations with their paging or MMU logic to get beyond the 16 bit address range. most were only compatable with that makers design and some were much to difficult to use effectively.
Now I've used bare Z80 , Z180s , Z280s in large address space configurations such as Compupro, CCS and other designs. I've even added bank switched memory to 8085 based systems.
Prequalifier: CP/M-80 or clone and not CP/M+, MPM.
The question: Though there are systems with more than 64k of ram the only common use I've seen the "extra" beyond 64k ram used for was
RAMdisk. Were there any uses out there other than personal projects that used CP/M-80 and memory beyond 64k? I suspect no but, I'm curious.
