Peter Evans 851bc85860 We should print the final line if from is still >= to

16.

Peter Evans 91291be889 Draw the full screen at boot time to emulate initial look

Peter Evans b2df144850 Remove blank-space render to speed up render time 2018-03-07 00:15:25 -06:00
Peter Evans 7edf0c5dbd Display @ symbols on startup 
There's actually a lot going on here to make the @ symbol display
happen.

The @ symbols are the visual representation of NUL-character bytes. They
are inverse video, as dictated by the Apple //e technical reference. As
part of the bootup sequence, those bytes are overwritten with space
characters.

As part of the work, we now have a table of rows and columns that map to
display buffer addresses.
