   Hello, and I screwed up on my OP.  I should've said "Quick Brown Box".   
   Back when these were on the market IIRC although the internal backup   
   battery would last a while it wasn't easily replaced.  So these weren't   
   flash-based.  I think the carts also came with a word processor.  Turns   
   out Googling on some non-usenet Commodore forums reveals that the topic   
   has been addressed.  Someone even had a schematic shown.   
      
   Come to think of it a better way would be to incorporate flash memory   
   that, like a USB flash drive, could be plugged into the ROM   
   expansion/game port.  Thanks for the quick reply.  Sincerely,
