7 screens of 58 lines each (2320 bytes each).

screens start at $8000, end at $bf6f.
display list goes at $bf70, ~40 bytes.
status lines (80 bytes) go at ~$bf98.

whoops. the screens can't be contiguous with a standard display list
due to the 4K boundaries at $9000, $a000, $b000. so we'll need each
one to have its own 40-byte display list.
