MIT's “Small ITS” Logo timesharing system

Wikipedia seems to suggest a bunch of versions of it were called LOGO, but as its not an acronym I think it probably makes little sense.

When I was working at BBN in 1978, in part on a LOGO project, the official spelling was in CAPS.

Don't forget, in those days, a lot of devices were upper-case only. Hence, even in the 1970s, many people said `FORTRAN' and `COBOL'.

I think it is just a matter of which presentations you remember the best. In the video below, there are a couple of places where it is all caps. I'm not sure I recall anything not in all caps on a Commodore 64. Not that I spent much time on one, but it was pretty much my only exposure to Logo.

The only implementations I ever used, PDP-10 and Atari 800 only had upper case so it had to be written LOGO.

Like ARPANET, in those case insensitive days we really didn’t think about it. Multics was case-sensitive, and it felt weird.
