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,
