That would be cool!
just a new menu option for "activate changes"!
I've modified the circuit I found by adding battery backup to the RAM
(62256's).  I need to look at the software they have and see if it let's you
byte-poke or if you have to do a full dump each time...  I guess new
software could be written to do one location at a time!
