Complete 2600 memory map at http://web.mit.edu/ecwilkso/www/VCS_hardware.

Once again (but probably not for the last time), I'll point people to the
*complete* VCS memory map:  http://web.mit.edu/ecwilkso/www/VCS_hardware
There you'll find everything you ever wanted to know about memory location
$xxxx.

Is stella search working yet, BTW?  I've pointed out the memory map several
times...would be nice if people could find references to it and everything
else discussed here.
