It's interesting that the 1964 CTSS manual† linked from the article (OCR'ed by Google††) uses "login", one word, no blank. See page 6 (page 14 of the PDF). I knew about ships' logs, but I didn't know that the word "log" originated from the use of a wooden log tossed overboard attached to a knotted rope, so that the observed speed could be entered into a book that eventually came to be known as a ship's log. Also interesting in that manual is that each "segment" of a command (what we now call a token) was six characters, blank-padded. The 7094 had 36-bit words and 6-bit bytes. †http://bitsavers.trailing-edge.com/pdf/mit/ctss/CTSS_ProgrammersGuide.pdf http://bitsavers.trailing-edge.com/pdf/mit/ctss/CTSS_Program... ††http://webcache.googleusercontent.com/search?q=cache:SapGOxkAdpwJ:www.bitsavers.org/pdf/mit/ctss/CTSS_ProgrammersGuide.pdf+&cd=1&hl=en&ct=clnk&gl=us http://webcache.googleusercontent.com/search?q=cache:SapGOxk...
