You could buy a board called Integra-B to expand a model B. https://www.youtube.com/watch?v=lT07uPRRPfU https://www.youtube.com/watch?v=lT07uPRRPfU A few games required some extra RAM.

I'm now actually curious if adding too many ROMs would make the * commands noticeably slower (the OS would look for the commands in the ROMs, one by one, until it found the code to handle them).
