Thanks for the pointer. It was good reading and a welcome reminder as
these days I'm actually doing instruction set design (not intended to
be user accessible, but we all know how intentions like that fair) and
we are trying to fit things in an 8/16 bit world. It gives me a good
argument for laying down some 32 (and 64 bit) address instructions,
even though on the first implementation, the machine will just barely
have 12 bits of address space, and thus they won't get used.


Thanks,
-Chris
