Hey man!  There will be a day when I understand all of your acronyms, but even
if I did, I would not condone the use of your "hypothetical" essay to show off
your apparent knowledge.  Go daydream somewhere else.

God how classic!  Patents do not run out that quickly, and even if they did,
they can be renewed.  A nice 386ish chip based on the 6502???  Gimme a break.
IF you wanted to design a new 65xx(x), you would want it to emulate a 65816
and also be able to run in a 100Mhz DSPish mode.  But, the //gs is the last
Apple ][, due to its inherent back-compatibility requirement.  Wait for the
PowerPC, at which time you can EMULATE an '816 and still have it run faster
than the fastest GS ever went.  Or, god forbid you actually want more power
than that, you can actually have a screen that's not limited to 640x200 and
a 1Mhz, 8-bit bus rate.
