Where in the World is Carmen Sandiego? Many of us asked that back in the 1980s as we learned our international geography through a computer game. If you played it on the Commodore 64, this is the font used on the computer readouts, and yes it was proportionally spaced! Which would be why it wasn't resource-ripped before. I had enough screen shots to work with, then worked out what the missing punctuation marks might look like.
Computer System Primer is an educational-styled free font which spoofs Computer System 5×20. It is a font entirely made by me.
This is a clone of Computer System 5x20A vertical take on Morse code. These glyphs are read left-to-right from the bottom up and spaced so that 1 pixel = 1 unit of time, whether moving horizontally or vertically. Letters have 3 spaces between them and words have 7 spaces.
The result is a concise design that can easily be fed to tone-generation or image-to-audio software (e.g., AudioPaint) to produce accurately encoded & timed Morse code, no matter the frequency (speed) of the transmission. You can use this principle to create and place messages into music or games, make messages match a tempo or beat, arpeggiate words and turn them into music or sound effects, and much more.
The name is a pun. :P

21NOV2018: I've recently learned that many radio stations use an expanded version of the International Morse Code, adding many symbols and punctuation to it. Though these new glyphs are not part of the standard, they are commonly used and agreed on, so I will keep adding them as I find them.
