Hi Cameron,

indeed an intriguing project :-)

Outside the 6502 something like this exists - my selfbuilt 6502 machine
has an MMU with virtual memory as far as a 6502 is capable of it. And
IIRC I have a modified VICE version on my 6502 pages that emulates
exactly this machine. Of course putting this into a 6502 itself
is of course much more interesting :-)
