----------
You have a little of each.  There are 399 possible pixel locations,
since the upper half of the double-height pixel can be on any line
except the bottom line. But, the screen is only 200 pixels high.
What you do about overlapping pixels has not been described in anything
I've seen here -- I suppose the later plotted pixel would overwrite
the earlier.  You could probably use this trick, with cleverly
designed fonts, to get 25x80 characters that were better than the
standard IBM color adapter but not as good as a Mac.  This might be a
reasonable compromise.  On the other hand, if I were designing a
text oriented program for a machine I knew to have 400 lines of
vertical resolution, I would want to use more than 25 lines of
text, sacrificing some text quality for quantity.  The main problem
with current text screens, on personal computers or terminals,
is that you can't get enough on them to make windowing really
useful.  The tall pixel idea really doesn't do anything to make
the Amiga better suited for answering that problem.
