d9527db033 Retrieve the 16-bit PC address.

ignored the LSB at $FFFD.

834959c10a Add rom, ram2 bank memory; modify read/write sig 
The signature for read/write map functions now accepts a void pointer so
that we can pass in the machine that those functions may need to know
about. This is a bit hairy, but allows us to avoid the need for a
yet-uglier global variable.

b2c1bd9e6d Hello world, in rendered text; use nearest pixel sampling 
The scale change removes some blurriness that we saw when copying pixels
from the bitmap font into the renderer.
