I examined sizes.txt as well. I agree that Parker
Brother's E0 bankswitching is a little complicated but
it's obviously not as complicated as the M-Networks
E7. The way E0 is described, it sounds as if each
segment is supposed to point to the next segment and
the last segment points to the first. Whether or not
it's supposed to decrease the use of the LDA $1FEx
statements, I don't know. But I'm not a seasoned
programmer anyway. :-) I'm always glad to learn
something new.
