Yes, that's what I like about - no external address bus.  Reduced circuit
complexity, lower cost, higher reliability, and fewer part sourcing
issues.  Way back in old times, a decent BASIC interpreter could run in
64K of RAM + ROM.  I don't want to program in BASIC, but a language that
calls itself small and embeddable (i.e. Lua) should really be that.  There
are folks who are running Lua (or eLua) on single-chip ARM systems.  PIC32
with it's MIPS architecture should be just as capable as that.  What's the
hold-up?
