If the programmer isn't confident waddling through Galleon's code, this illustration was the only way to work things so the "built-in font" could be displayed at a larger size. 
A few decades back I've written a program in C that works on 16-bit MS-DOS that looked at the BIOS locations of the 8x8 font, and printed out short words with various characters and colors. I got carried away and started saving them as BSAVE images of 4000 bytes. There wasn't much to do with those files, unfortunately.
EDIT: Oh I just noticed the trick in BAM, using POINT() with -- SCREEN 0. Whoa wait until Pete finds out about this!
