This is the screen font from the IBM 5100 Portable Computer. It is uppercase-only, and has a large repertory of APL-related characters as well. Of note is that no two adjacent horizontal dots are ever both active, because the font might have also been intended to be used with a dot-matrix printer.
Recreated character set of the Brother EP-20/22 Electronic Thermal Typewriter (1983).
Square-pixel variation also available.
This is a rendition of one of A. V. Hershey's dot fonts from his 1967 paper "Calligraphy for Computers", the "Mathematical" (serif) font. This version is really a hybrid of the original "Mathematical" and "Cartography" fonts, having some symbols such as the circle drawing and map symbols that the "Mathematical" font originally lacked.
This is a clone of Hershey Dot Cartographic
