This is the font used in my Scratch projects that use SSEGA OS, SSEGA OS 92, and SSEGA OS CD (https://scratch.mit.edu/projects/938150503/ https://scratch.mit.edu/projects/938615942/ https://scratch.mit.edu/projects/939136020/). It has a lot of characters in a 4x5 bounding box.
The default font used by Adafruit's GFX library. The hex codes correspond to the cp437(true) chart on page 16:

Hex codes with bit[0] = 0, 1, 8, 9 were unavailable, so bit[2] is set as 1.
(Ex: 0x0001 => 0x0101)
