It's similar, except for the fact that in your version the
two buffers have the same weight, so you can use only black-
grey-white instead of black-dark grey-bright grey-white. If
I remember well, a three-byte mixing mask was used with
every 3rd bit set, and it was rotated by one bit for every
refresh, so one of the buffers had each of its pixels
displayed twice as long on average than those of the other
buffer.
