One can really get bogged down in fonts. (-:

If you want a quick improvement over that 8by8 IBM ROM font, I suggest two things:

1. Switch to a 16by16 square.

2. For the ASCII range, go with one of the old home computer fonts, rather than IBM ROMs. Viznut has .hex files for Commodore PET and BBC Micro graphics modes squirrelled away inside Unscii.

I've done the work of upscaling the 8by8 PET font to 16by16, and it works quite nicely as a monospace square font. These old home computer fonts were of course designed to. Whereas in the world of VGA you're soon in trouble with glyphs designed for 9by16.
