This involves hardware as well as software but I don't see a better section
for it.

Yep, many Smalltalk implementations have an image file that holds the
state of all the objects in the system (code and data), and a virtual
machine that loads and saves the image file as the method of

ETHNO runs on my old Toshiba Satellite T2100, 80486, 8 MiB RAM.
So non-volatile memory now available from Ramtron should be adequate.
Each of these is 2 MiB.

Interfacing 4, 8 or even 16 of them to a CPU must be possible.  That
would easily support ETHNO; possibly A2.  Wear leveling is not involved. 
No boot loading; instant on.  Filesystems needed only for access to large
data sets, legacy data and data from external sources.

Wouldn't be feasible for most conventional systems where nundreds of
MiBs are used.  But we are interested in efficiency rather than grandiosity.
