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.<br>

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.<br>
<br>
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.<br>
<br>
Apparently this is covered by the blanket license grant making all
DEC PDP-8 software public domain. (Thanks, Bob!)<br>

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.

<div>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.</div>

<div>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.</div>
<div><br>

<div>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.<br>
