This is a reproduction of the 6x13 font on the old Apollo workstations.  I've always liked this font - it's readable, but quite a bit narrower than other monospaced fonts that I've found.  Trouble is, as monitors have gotten higher-resolution and my eyes have gotten lower-resolution, I'm having trouble reading the original bitmap font.

This font is almost identical to "6x13 redux", except (a) a few glyphs were slightly different, and (b) "6x13 redux" isn't monospaced.

Size 12 (under Windows 10 at least) is virtually identical to the original bitmap.  Size 15 scales pretty well, but sizes in between 12 & 15 don't look that great.
