c7aa9e9fc3 Resolver may be NULL; don't call if so 
This change also registers a default value for operand (0).

700bc31465 Copy system rom into $C800..$CFFF; document. 
Things are getting a little hairy...at least, as to my own
comprehension. Documentation is a must.

06d37d24d7 Allow us to call objstore_init more than once. 
This also separates some code into objstore_ready().

Peter Evans
e7a404508e Add init functions for disk2, sys rom 
Also move the defines for bank offset, rom size, etc. into apple2.mem.h
which makes a little more sense.

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.
