Yes, we had a system which swapped to floppies also (MINC-11/RX02,
actually we had a system up which did it with non-dma RX01s but
that was too painful to think about...)

Hmm, if the problem is relocation how awful would swapping to memory
be? That is, rather than swapping in and out of a floppy you just
rearrange the processes in memory on context switch. Oh, it won't
be dazzling, but certainly many times faster than a floppy.

Or maybe I should just throw my hands up and suggest getting the right
hardware to do the job, the law of diminishing returns slowly comes
into play (especially because one strongly suspects that by the time
the bugs are out of an O/S and possibly a C compiler which meets the
above requirements ATARI or someone like them will have announced a
2MB systems with MMU and reasonable hard disk for under $2K [oops, I
think that's here already :-])
