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.

A typical monospaced font, 5x7. Somewhat, 80s style.

This is another clone of Monkey (my monospace lanky font); it should be very similar to the original except for the lower x-height and the added accented characters (More Latin/Latin-1, Latin Extended A, Latin Extended B, and now Even More Latin/Latin Extended Additional). It is 16 blocks tall and 6 blocks wide; all letters without diacritics are at most 9 above the baseline and at most 3 below, but the accents push the height of a letter up by 3 blocks (or rarely 4), and the box drawing characters extend even higher, to 16 blocks from descender to the highest point. This font uses the FontStruct 2x2 filter method with plenty of composite and stacked bricks, which lets the curves look good at large sizes while remaining sharp on the screen at normal sizes. Mandrill will look strange in the FontStruct preview if you zoom in or out, but if you download it, it will look sharp at size 16 or 12 (depending on the program).

Monospace version of Interface.

A typeface designed to be ideal for coding applications. This typeface aims to be a simple pixel font that can both easily be read at small sizes and also look classy at the same time. Each character is designed to have its own unique shape to avoid confusing one character with another (something I found to be a common issue with most pixel fonts).
