After rereading the message I just replied to, I noted a possible
misconception regarding the bitter chip.
Blit is a mneumonic for block bit transfer. It refers to the moving
of a big chunk of graphics on one or more bitplanes to another section
of the screen. An offline blitter chip would make text scrolling
faster, but it wouldn't do much for the plotting unless plotting is done
by copying a small section of graphics (the letter) to the spot on the
screen where you want it.
