i see those codes like a "blast from the past"
Phhft! 'a blast from the past' was TWO level Morse and several European contemporaries - even
predecessors, the French five-level Baudot with its clever 'shift in' and 'shift out' option still more widely used in my youth than UNIVAC 6-bit FIELDATA or either of IBM's BCDIC and EBCDIC munges.
ASCII was not even expected to survive, let alone prevail, and might NOT have done had IBM not adopted it for 'small iron' machines that were to prove huge sellers. "Word Processors" that were actually better 'computers' at CPU-level than many computer-computers of the era, plus a 'mid frame' barely able to reboot in 13 hours after a crash.
Didja know that often despised IBM "AIX" is the only commercial UNIX to have ever earned SERIOUS money?
Or that it did so by outselling all other "Unices"
combined and carrying a rather average-otherwise line of 'puters on its broad-shouldered
back? GE-Honeywell-Bull did a better 'hardware' implementation - shared patents and all - back in that era.
Thank also 'Plan 9' team member notes on a fast-food napkin that led in mere days to UTF-8 and -16 - either of them able to cover all known languages and character sets of mankind, current, fossilized, or future.
