I have put a copy of the original ASCII standard (scanned images) at
http://www.cogsci.ed.ac.uk/~richard/ascii.tar
I don't remember where I got it from.

I found the same document online at http://www.worldpowersystems.com/J/codes/index.html Incidentally, does anyone know anything about the 1961 DoD 8-bit character set standard it refers to? This does not appear to say anything about LF vs "Newline" (as either a name or a function), though the 1986 version of ASCII deprecates it, so was most likely acknowledged in versions between these in response to practices on OSes such as Multics. ECMA-6:1973 acknowledges it, for example (the fourth edition at https://www.ecma-international.org/publications/standards/Ecma-006-arch.htm). ^ permalink raw reply [flat|nested] 4+ messages in thread

[…] (p. 420) I found a pre-ASCII standard proposal at https://archive.org/details/enf-ascii-1961-09 that refers to "MIL-STD-188A". Googling *that* finds stuff referring to Fieldata, so that's probably what it's referring to. Fieldata does have a "Special" control character immediately before DEL. And now that I check again, the WPS page does say "For all intents and purposes "FIELDATA" today refers to the character code. It, or a minor variant, is sometimes called the "DoD standard 8-bit code". ^ permalink raw reply [flat|nested] 4+ messages in thread
