My god, look at this absolutely lovely* Venn diagram showing the overlap (and non-overlap) of characters supported by various popular computing systems in 1972. Notably, the ¢ symbol is supported in IBM's EBCDIC but not in anything else. (ASCII here means what we now think of as 7-bit ASCII, only the first 128 ASCII codes. 256-character ASCII wouldn't be formally standardized until 1987 in ISO 8859!)

*lovely... but maddening
@darius "basic ebcdic" is a serviceable tongue twister
God this reminds me of the x86 SIMD instruction set Venn diagram 🤦🏻♂️
@darius odd that the asr33/35 character set included [ and ]. Those keys aren't present on the teletype that I restored.
@darius although perhaps alternate type wheels had those characters.
@darius at&t out here with backwards and upwards arrows but no forwards or downwards arrows...... galaxy brain
@darius I also love that basically nobody had lower case until ascii
Technically the 8-bit versions was never called ASCII, were they? There were variations called extended-ASCII but they were all different.
I think ISO 8859 wss only referred to as ASCII informally.
