Also, for decades teletypes used 5-bit 'Baudot' codes. 2^5 = 32. (LTRS) A shift-key (FIGS) could be used for number digits and most punctuation. (Telegrams shown in old movies are almost always upper-case only.) 7-bit ASCII (2^7 = 128) didn't start to show up until 1963. (Starting the arguments.) Funnier: the machines used gears inside that limited how fast it could type. (60wpm on the low-end ... Which also made it hard to 'read the mail' of commercial carriers that used 66-75wpm machines.) |
