TSS-8 was an official product. I may be confusing / mixing memories

truth, I'm not sure I c |an help much as I was late to TSS-8).
All of the TSS/8 customers received source listings. There's a set of
sources available for download apparently from someone who retyped the
source. TSS/8 was definitely a real DEC product, but I doubt it was
ever sold unbundled from hardware. For reference, my first job at DEC
was in the group that did worldwide support for PDP-8 systems, including
the schools running TSS/8.
Anyway, I always thought it was created by a customer and DEC
educational system group redistributed it. ???Maybe try checking some
DECUS archives from the late 1960s/early 1970s if possible???
The ideas around TSS/8 (timesharing mode) came from a research project
at CMU. CMU and DEC collaborated to build the initial TSS/8 system.
You may be thinking of EDUsystem-50, which was the TSS/8 rebranding by
the edu group. Several EDUsystem variants existed, from single-user
BASIC systems up to TSS/8 multiuser.
Apparently this is covered by the blanket license grant making all DEC
PDP-8 software public domain. (Thanks, Bob!)

<https://tangentsoft.com/pidp8i/wiki?name=Home>. I've been going
through the files we distribute to make sure we have proper licenses
for them and have come up short on a few things: the TSS-8 and ETOS
disk images. I've simply been unable to find any indication online
that they were ever licensed for free redistribution.
I'm posting here because this list was recommended as a place where
someone might know whether these OSes were ever formally licensed for
free redistribution.
Since TSS-8 was a DEC product, I'm hoping that it was released under
the "hobbyist" licenses they offered at some point. I expect I could
sign up for the current OpenVMS hobbyist license, but I have no
interest in agreeing to it just to see if it covers this software.
Perhaps someone who has agreed to it could confirm this guess? The
web site seems to just talk about VMS, which I have no interest in.
As for ETOS, that wasn't a DEC product, so I have no better guess for
where to go trying to find a license for it other than web search
engines, and I've already struck out there.
