It is also worth adding that bit 0 of port # EFF7 reserved
under other additional graphics mode - the attribute to a byte
ie addresses # 4000 - # 57FF is standard sinklerovsky screen,
and the addresses # 6000 - # 77FF - corresponding to each byte
from the main screen attribute byte, and in this byte bits have
the same purpose as in the standard attributes for except for
bits 6 and 7, which are now responsible, respectively, for
PAPER BRIGHT and INK BRIGHT. Refinement consists of a single
chip - 1533KP11 and allows without difficulties to effects such
as MultiColor without spending a single stroke CPU (except, of
course, the premise of information in the display area).
