I suppose Peter's definition of "same computer" is one that runs the same
software.  If the A2000 had an MMU and ran Unix, then it would certainly
be a "different" computer.  When DEC came out with the VAX, they provided 
some crude PDP11 compatibility mode, but as far as I know, no upgrade.  When
DEC came out with the VAX 785, they certainly did have an upgrade
available for the 780.  But then, the 785 was "the same computer" 
as the 780 given your definition.  Basically, it comes down to whether
it is reasonable to expect a computer company to provide an upgrade path
to a "different" computer.  Personally, I don't think you can expect any
company that wants to stay in business to provide such an upgrade (they
would be like a lightbulb company which replaced your bulbs when they
burnt out, or perhaps produced bulbs which never burnt out).  What you want
as an "upgrade" is certainly wishful thinking.
