2K Character RAM at write only address $f000-$f7ff looks to be organised
64x32 chars with the screen rotated through 90 degrees clockwise. There
appears to be some kind of attribute(?) RAM above at $f800-$ffff organised
in the same manner.

$e000 looks like sprite ram, setup routines at $0008.
Partial hand-made schematics don't show a buffer, but the games most
definitely need it. Could be the second half of the ram, which seems
otherwise unused, but it would be weird bandwidth-wise. It's not
double-buffering through page swapping, sprite updates are
incremental.
