Mike,

Sometimes you just don't have enough room and you end up having to spend a
lot of extra time (and code) switching between banks.

I did a cable tv converter ('57) once which had 25% of its code being
bank-related, either ROM or RAM banks (it had 48 words of ROM free).
Changed to a '72 (for other reasons) and was able to add a ton of
functionality.  500 words is a lot of code!

And that was 25% after removing redundant stuff and swapping things (RAM,
ROM) around in memory so as to minimize it.
