Okay, I need to call everyone on this even though I know it's going to 
stir up a flame war. Almost nobody who has responded thus far has 
demonstrated that they actually read my original query completely.

My question was simple. Where does the font data come from when the GIME 
is displaying a hardware text mode.

The answer to the original question appears to be "the font data used by 
the GIME in hardware text modes is internal to the GIME". This is what I 
originally thought for various reasons related to design complexity, etc.

As explained in my original message, my confusion came from the fact 
that at least some versions of Mess do things differently - that is, 
they take the font data for the hardware text modes from the HPRINT font 
data in the 32K internal ROM. This is almost certainly the wrong thing 
to do given the preceding answer and it looks like later versions have 
attempted to correct that deficiency.

Now don't get me wrong, there has been some good information which will 
likely be of use to others, including descriptions of how the various 
resolution and mode settings interact and so on. However, none of that 
is relevant to my original question and if I did not already understand 
basically how it all works, it would only have served to confuse me further.
